Pipe operator
Usage
lhs %>% rhs
Get a tidy data frame of classifications of all functions used in your analysis
Description
Get a tidy data frame of classifications of all functions used in your analysis
Usage
get_classifications(lexicon = NULL, include_duplicates = TRUE)
Arguments
lexicon
Character. The classification lexicon to retrieve. Either
"crowdsource" or "leeklab". If NULL (default), will return all lexicons.
include_duplicates
Logical. Indicates whether to include all functions
and classifications along with their score (default, TRUE) - this may
result in multiple lines (with multiple classifications) for a single function.
If FALSE, the most prevalent classification will be selected.
Value
A tbl_df with columns:
-
func: the function -
classification: the classification
If include_duplicates = TRUE, will include a column:
-
score: the score
If lexicon is NULL, will include a column:
-
lexicon: the classification lexicon
Examples
# Get a data frame of all classifications
get_classifications()
# Get a data frame of the most prevalent classifications
get_classifications(include_duplicates = FALSE)
# Get a data frame of only `leeklab` classifications
get_classifications("leeklab")
Get a tidy data frame of a "stopword" lexicon for R functions
Description
Get a data frame listing one function per row.
Usage
get_stopfuncs()
Value
A tbl_df with one column:
-
func: the function identified as a "stopword"
Examples
get_stopfuncs()
List packages
Description
List packages
Usage
ls_packages(x)
Arguments
x
an R call or list of R calls
Value
Character. Vector of packages called.
Examples
ls_packages(
list(
quote(library(tidycode)),
quote(library(purrr)))
)
Read R file(s) as a tidy data frame
Description
Read R file(s) as a tidy data frame
Usage
read_rfiles(...)
Arguments
...
One or more quoted R file paths to read
Value
A tidy data frame, a tbl_df, with one row per R call. There will be three columns,
-
file: the path of the original R file -
expr: the R call -
line: the line of the R call
Examples
d <- read_rfiles(
tidycode_example("example_plot.R"),
tidycode_example("example_analysis.R")
)
Get path to example file
Description
tidycode comes bundled with a few small files to use in examples. This function makes them easy to access.
Usage
tidycode_example(path = NULL)
Arguments
path
Name of file. If NULL, the example files will be listed.
Examples
tidycode_example()
tidycode_example("example_plot.R")
Unnest R calls
Description
Unnest R calls
Usage
unnest_calls(.data, input, drop = TRUE)
Arguments
.data
A data frame
input
Input column that contains an R call or list of R calls to be split into individual functions
drop
logical. Whether the original input column should be dropped.
Value
The original data frame with an additional three columns:
-
line: the line number of the call -
func: the name of the function called -
args: a list of arguments
Examples
d <- read_rfiles(tidycode_example("example_plot.R"))
# Unnest a model call
d %>%
unnest_calls(expr)
# Unnest a model call and keep the call itself using the drop parameter
d %>%
unnest_calls(expr, drop = FALSE)
