)
appendHtmlTableStyle(
 x,
 align = NULL,
 align.header = NULL,
 align.cgroup = NULL,
 css.rgroup = NULL,
 css.rgroup.sep = NULL,
 css.tspanner = NULL,

 padding.rgroup = NULL,
 padding.tspanner = NULL,
 spacer.celltype = NULL,
 spacer.css.cgroup.bottom.border = NULL,
 spacer.css = NULL,
 spacer.content = NULL
)

Arguments

Details

The function stores the current theme (see setHtmlTableTheme() ) + custom styles to the provided object as an base::attributes() . It is stored under the element htmlTable.style in the form of a list object.

Value

x with the style added as an attribute that the htmlTable then can use for formatting.

The css.cell argument

The css.cell parameter allows you to add any possible CSS style to your table cells. css.cell can be either a vector or a matrix.

If css.cell is a vector, it's assumed that the styles should be repeated throughout the rows (that is, each element in css.cell specifies the style for a whole column of 'x').

In the case of css.cell being a matrix of the same size of the x argument, each element of x gets the style from the corresponding element in css.cell. Additionally, the number of rows of css.cell can be nrow(x) + 1 so the first row of of css.cell specifies the style for the header of x; also the number of columns of css.cell can be ncol(x) + 1 to include the specification of style for row names of x.

Note that the text-align CSS field in the css.cell argument will be overriden by the align argument.

Excel has a specific css-style, mso-number-format that can be used for improving the copy-paste functionality. E.g. the style could be written as: ⁠css_matrix <- matrix( data = "mso-number-format:\"\\@\"", nrow = nrow(df), ncol = ncol(df))⁠

Output an HTML table

Description

Generates advanced HTML tables with column and row groups for a dense representation of complex data. Designed for maximum compatibility with copy-paste into word processors. For styling, see addHtmlTableStyle() and setHtmlTableTheme() . Note: If you are using tidyverse and dplyr you may want to check out tidyHtmlTable() that automates many of the arguments that htmlTable requires.

 rowlabel = NULL,
 caption = NULL,
 tfoot = NULL,
 label = NULL,
 rgroup = NULL,
 n.rgroup = NULL,

 escape.html = FALSE,
 ...
)
## Default S3 method:
htmlTable(

 escape.html = FALSE,
 ...
)
## S3 method for class 'htmlTable'
knit_print(x, ...)
## S3 method for class 'htmlTable'
print(x, useViewer, ...)

Arguments

Value

Returns a formatted string representing an HTML table of class htmlTable.

Multiple rows of column spanners cgroup

If you want to have a column spanner in multiple levels (rows) you can set the cgroup and n.cgroup arguments to a matrix or list.

For different level elements, set absent ones to NA in a matrix. For example, cgroup = rbind(c("first", "second", NA), c("a", "b", "c")). And the corresponding n.cgroup would be n.cgroup = rbind(c(1, 2, NA), c(2, 1, 2)). for a table consisting of 5 columns. The "first" spans the first two columns, the "second" spans the last three columns, "a" spans the first two, "b" the middle column, and "c" the last two columns.

Using a list is recommended to avoid handling NAs.

For an empty cgroup, use "".

The rgroup argument

The rgroup groups rows seamlessly. Each row in a group is indented by two spaces (unless the rgroup is "") and grouped by its rgroup element. The sum(n.rgroup) should be zr3ywKOjLZACY4j7TuGXu4v6I8wVWuKy-\leq matrix rows. If fewer, remaining rows are padded with an empty rgroup (""). If rgroup has one more element than n.rgroup, the last n.rgroup is computed as nrow(x) - sum(n.rgroup) for a smoother table generation.

The add attribute to rgroup

To add an extra element at the rgroup level/row, use attr(rgroup, 'add'). The value can either be a vector, a list, or a matrix. See vignette("general", package = "htmlTable") for examples.

• A vector of either equal number of rgroups to the number of rgroups that aren't empty, i.e. rgroup[rgroup != ""]. Or a named vector where the name must correspond to either an rgroup or to an rgroup number.

• A list that has exactly the same requirements as the vector. In addition to the previous we can also have a list with column numbers within as names within the list.

• A matrix with the dimension ⁠nrow(x) x ncol(x)⁠ or ⁠nrow(x) x 1⁠ where the latter is equivalent to a named vector. If you have rownames these will resolve similarly to the names to the list/vector arguments. The same thing applies to colnames.

Important knitr-note

This function will only work with knitr outputting HTML, i.e. markdown mode. As the function returns raw HTML-code the compatibility with non-HTML formatting is limited, even with pandoc.

Thanks to the the knitr::knit_print() and the knitr::asis_output() the results='asis' is no longer needed except within for-loops. If you have a knitr-chunk with a for loop and use print() to produce raw HTML you must set the chunk option results='asis'. Note: the print-function relies on the base::interactive() function for determining if the output should be sent to a browser or to the terminal. In vignettes and other directly knitted documents you may need to either set useViewer = FALSE alternatively set options(htmlTable.cat = TRUE).

RStudio's notebook

RStudio has an interactive notebook that allows output directly into the document. In order for the output to be properly formatted it needs to have the class of html. The htmlTable tries to identify if the environment is a notebook document (uses the rstudioapi and identifies if its a file with and Rmd file ending or if there is an element with html_notebook). If you don't want this behavior you can remove it using the options(htmlTable.skip_notebook = TRUE).

Table counter

If you set the option table_counter you will get a Table 1,2,3 etc before each table, just set options(table_counter=TRUE). If you set it to a number then that number will correspond to the start of the table_counter. The table_counter option will also contain the number of the last table, this can be useful when referencing it in text. By setting the option options(table_counter_str = "<b>Table %s:</b> ") you can manipulate the counter table text that is added prior to the actual caption. Note, you should use the sprintf() ⁠%s⁠ instead of ⁠%d⁠ as the software converts all numbers to characters for compatibility reasons. If you set options(table_counter_roman = TRUE) then the table counter will use Roman numerals instead of Arabic.

Empty data frames

An empty data frame will result in a warning and output an empty table, provided that rgroup and n.rgroup are not specified. All other row layout options will be ignored.

Options

There are multiple options that can be set, here is a set of the perhaps most used

• table_counter - logical - activates a counter for each table

• table_counter_roman - logical - if true the counter is in Roman numbers, i.e. I, II, III, IV...

• table_counter_str - string - the string used for generating the table counter text

• useViewer - logical - if viewer should be used fro printing the table

• htmlTable.cat - logical - if the output should be directly sent to cat()

• htmlTable.skip_notebook - logical - skips the logic for detecting notebook

• htmlTable.pretty_indentation - logical - there was some issues in previous Pandoc versions where HTML indentation caused everything to be interpreted as code. This seems to be fixed and if you want to look at the raw HTML code it is nice to have this set to TRUE so that the tags and elements are properly indented.

• htmlTableCompat - string - see parameter description

Other

Copy-pasting: As you copy-paste results into Word you need to keep the original formatting. Either right click and choose that paste option or click on the icon appearing after a paste. Currently the following compatibilities have been tested with MS Word 2016:

• Internet Explorer (v. 11.20.10586.0) Works perfectly when copy-pasting into Word

• RStudio (v. 0.99.448) Works perfectly when copy-pasting into Word. Note: can have issues with multi-line cgroups - see bug

• Chrome (v. 47.0.2526.106) Works perfectly when copy-pasting into Word. Note: can have issues with multi-line cgroups - see bug

• Firefox (v. 43.0.3) Works poorly - looses font-styling, lines and general feel

• Edge (v. 25.10586.0.0) Works poorly - looses lines and general feel

Direct word processor opening: Opening directly in Libre Office or Word is no longer recommended. You get much prettier results using the cut-and-paste option.

Google docs: Copy-paste directly into a Google docs document is handled rather well. This seems to work especially well when the paste comes directly from a Chrome browser.

Note that when using complex cgroup alignments with multiple levels not every browser is able to handle this. For instance the RStudio webkit browser seems to have issues with this and a bug has been filed.

As the table uses HTML for rendering you need to be aware of that headers, row names, and cell values should try respect this for optimal display. Browsers try to compensate and frequently the tables still turn out fine but it is not advised. Most importantly you should try to use ⁠<⁠ instead of < and ⁠>⁠ instead of >. You can find a complete list of HTML characters here.

Lastly, I want to mention that function was inspired by the Hmisc::latex() that can be an excellent alternative if you wish to switch to PDF-output. For the sibling function tidyHtmlTable() you can directly switch between the two using the table_fn argument.

string Returns the html string for the ⁠<thead>...</thead>⁠ element

Detects if the call is made from within an RStudio Rmd file or a file with the html_notebook output set.

Description

Detects if the call is made from within an RStudio Rmd file or a file with the html_notebook output set.

Usage

prIsNotebook()

Merges multiple colors

Description

Uses the colorRampPalette() for merging colors. Note: When merging more than 2 colors the order in the color presentation matters. Each color is merged with its neigbors before merging with next. If there is an uneven number of colors the middle color is mixed with both left and right side.

Usage

prMergeClr(clrs)

Arguments

Value

character A hexadecimal color

Makes sure the input is correct

Description

Checks and converts dimensions into something the htmlTable() is comfortable with.

Usage

Set or update theme for htmlTable()

Description

The theme guides many of the non-data objects visual appearance. The theme can be over-ridden by settings for each table. Too get a more complete understanding of the options, see addHtmlTableStyle() .

Usage

setHtmlTableTheme(
 theme = NULL,
 align = NULL,
 align.header = NULL,
 align.cgroup = NULL,
 css.rgroup = NULL,
 css.rgroup.sep = NULL,
 css.tspanner = NULL,
 css.tspanner.sep = NULL,
 css.total = NULL,
 css.cell = NULL,
 css.cgroup = NULL,
 css.header = NULL,
 css.header.border_bottom = NULL,
 css.class = NULL,
 css.table = NULL,
 pos.rowlabel = NULL,
 pos.caption = NULL,
 col.rgroup = NULL,
 col.columns = NULL,
 padding.rgroup = NULL,
 padding.tspanner = NULL,
 spacer.celltype = NULL,
 spacer.css.cgroup.bottom.border = NULL,
 spacer.css = NULL,
 spacer.content = NULL
)

Arguments

Value

An invisible list with the new theme

Theme options

The styles available are:

• standard: The traditional standard style used in htmlTable() since the early days

• ⁠Google docs⁠: A style that is optimized for copy-pasting into documents on Google drive. This is geared towards minimal padding and margins so that the table is as dense as possible.

• blank: Just as the name suggests the style is completly empty in terms of CSS. Positions for rowlabel and caption are set to bottom as these cannot be blank.

You can also provide your own style. Each style should be a names vector, e.g. c(width = "100px", color = "red") or just a real css string, ⁠width: 100px; color: red;⁠.

Examples

## Not run: 
setHtmlTableTheme("Google", align = "r")
## End(Not run)

See txtMergeLines()

Description

See txtMergeLines()

Usage

Generate an htmlTable using tidy data as input

Description

This function maps columns from the input data, x, to htmlTable() parameters. It's designed to provide a fluent interface for those familiar with the tidyverse ecosystem.

Usage

tidyHtmlTable(
 x,
 value,
 header,
 rnames,
 rgroup,
 hidden_rgroup,
 cgroup,
 tspanner,
 hidden_tspanner,
 skip_removal_warning = getOption("htmlTable.skip_removal_warning", FALSE),
 rnames_unique,
 table_fn = htmlTable,
 ...
)

Arguments

Value

Returns the HTML code that, when rendered, displays a formatted table.

Column-mapping

Columns from x are mapped (transformed) to specific parameters of the htmlTable() The following columns are converted to match the intended input structure:

• value

• header

• rnames

• rgroup

• cgroup

• tspanner

Each combination of the variables in x should be unique to map correctly to the output table.

Row uniqueness

Usually each row should have a unique combination of the mappers. Sometimes though rows come in a distinct order and the order identifies the row more than the name. E.g. if we are identifying bone fractures using the AO-classification we will have classes ranging in the form of:

• A

• A1

• A1.1

• A2

• A2.1

• A2.2

• B

• ...

we can simplify the names while retaining the key knowledge to:

• A

• .1

• ...1

• .2

• ...1

• ...2

• B

• ...

This will though result in non-unique rows and thus we need to provide the original names in addition to the rnames argument. To do this we have rnames_unique as a parameter, without this tidyHtmlTable we risk unintended merging of cells, generating > 1 value per cell.

Note it is recommended that you verify with the full names just to make sure that any unexpected row order change has happened in the underlying pivot functions.

Sorting

Rows can be pre-sorted using dplyr::arrange() before passing to tidyHtmlTable. Column sorting is based on arrange(cgroup, header). If you want to sort in non-alphabetic order you can provide a factor variable and that information will be retained.

Hidden values

htmlTable Allows for some values within rgroup, cgroup, etc. to be specified as "". The following parameters allow for specific values to be treated as if they were a string of length zero in the htmlTable function.

• hidden_rgroup

• hidden_tspanner

Simple tibble output

The tibble discourages the use of row names. There is therefore a convenience option for tidyHtmlTable where you can use the function just as you would with htmlTable() where rnames is populated with the rnames argument provided using tidyselect syntax (defaults to the "names" column if present int the input data).

Additional dependencies

In order to run this function you also must have dplyr, tidyr, tidyselect and purrr packages installed. These have been removed due to the additional 20 Mb that these dependencies added (issue #47). Note: if you use tidyverse it will already have all of these and you do not need to worry.

# Prep and select basic data
data("mtcars")
base_data <- mtcars %>%

SI or English formatting of an integer

Description

English uses ',' between every 3 numbers while the SI format recommends a ' ' if x > 10^4. The scientific form 10e+? is furthermore avoided.

Usage

txtInt(
 x,
 language = getOption("htmlTable.language", default = "en"),
 html = getOption("htmlTable.html", default = TRUE),
 ...
)

Arguments

Value

string

See Also

Other text formatters: txtMergeLines(), txtPval(), txtRound()

Examples

txtInt(123)
# Supplying a matrix
txtInt(matrix(c(1234, 12345, 123456, 1234567), ncol = 2))
# Missing are returned as empty strings, i.e. ""
txtInt(c(NA, 1e7))

A merges lines while preserving the line break for HTML/LaTeX

Description

This function helps you to do a table header with multiple lines in both HTML and in LaTeX. In HTML this isn't that tricky, you just use the ⁠<br />⁠ command but in LaTeX I often find myself writing vbox/hbox stuff and therefore I've created this simple helper function

Usage

txtMergeLines(..., html = 5)

Arguments

Value

string with asis_output wrapping if html output is activated

See Also

Other text formatters: txtInt(), txtPval(), txtRound()

Examples

txtMergeLines("hello", "world")
txtMergeLines("hello", "world", html=FALSE)
txtMergeLines("hello", "world", list("A list", "is OK"))

Formats the p-values

Description

Gets formatted p-values. For instance you often want 0.1234 to be 0.12 while also having two values up until a limit, i.e. 0.01234 should be 0.012 while 0.001234 should be 0.001. Furthermore you want to have ⁠< 0.001⁠ as it becomes ridiculous to report anything below that value.

Usage

txtPval(pvalues, lim.2dec = 10^-2, lim.sig = 10^-4, html = TRUE, ...)

Arguments

Value

vector

See Also

Other text formatters: txtInt(), txtMergeLines(), txtRound()

Examples

txtPval(c(0.10234,0.010234, 0.0010234, 0.000010234))

A convenient rounding function

Description

Regular round often looses trailing 0:s as these are truncated, this function converts everything to strings with all 0:s intact so that tables have the correct representation, e.g. txtRound(1.01, digits = 1) turns into 1.0.

Usage

txtRound(x, ...)
## Default S3 method:
txtRound(
 x,
 digits = 0,
 digits.nonzero = NA,
 txt.NA = "",
 dec = getOption("htmlTable.decimal_marker", default = "."),
 scientific = NULL,
 txtInt_args = getOption("htmlTable.round_int", default = NULL),
 ...
)
## S3 method for class 'table'
txtRound(x, ...)
## S3 method for class 'matrix'
txtRound(x, digits = 0, excl.cols = NULL, excl.rows = NULL, ...)
## S3 method for class 'data.frame'
txtRound(x, ..., digits = 0L)

Arguments

Value

matrix/data.frame

Tidy-select with data.frame

The txtRound can use data.frame for input. This allows us to use tidyselect patterns as popularized by dplyr.

See Also

Other text formatters: txtInt(), txtMergeLines(), txtPval()

Examples

# Basic usage
txtRound(1.023, digits = 1)
# > "1.0"
txtRound(pi, digits = 2)
# > "3.14"
txtRound(12344, digits = 1, txtInt_args = TRUE)
# > "12,344.0"
# Using matrix
mx <- matrix(c(1, 1.11, 1.25,
 2.50, 2.55, 2.45,
 3.2313, 3, pi),
 ncol = 3, byrow=TRUE)
txtRound(mx, digits = 1)
#> [,1] [,2] [,3]
#> [1,] "1.0" "1.1" "1.2"
#> [2,] "2.5" "2.5" "2.5"
#> [3,] "3.2" "3.0" "3.1"
# Using a data.frame directly
library(magrittr)
data("mtcars")
# If we want to round all the numerical values
mtcars %>%
 txtRound(digits = 1)
# If we want only want to round some columns
mtcars %>%
 txtRound(wt, qsec_txt = qsec, digits = 1)

Collapse vector to string

Description

Merges all the values and outputs a string formatted as '1st element', '2nd element', ...

Usage

vector2string(
 x,
 quotation_mark = "'",
 collapse = sprintf("%s, %s", quotation_mark, quotation_mark)
)

Arguments

Value

A string with ', ' separation

Examples

vector2string(1:4)
vector2string(c("a", "b'b", "c"))
vector2string(c("a", "b'b", "c"), quotation_mark = '"')
