Plot Methods for table Objects
Description
This is a method of the generic plot function for
(contingency) table objects. Whereas for two- and more
dimensional tables, a mosaicplot is drawn,
one-dimensional ones are plotted as bars.
Usage
## S3 method for class 'table'
plot(x, type = "h", ylim = c(0, max(x)), lwd = 2,
xlab = NULL, ylab = NULL, frame.plot = is.num, ...)
## S3 method for class 'table'
points(x, y = NULL, type = "h", lwd = 2, ...)
## S3 method for class 'table'
lines(x, y = NULL, type = "h", lwd = 2, ...)
Arguments
x
a table (like) object.
y
Must be NULL: there to protect against incorrect calls.
type
plotting type.
ylim
range of y-axis.
lwd
line width for bars when type = "h" is used in the 1D case.
xlab, ylab
x- and y-axis labels.
frame.plot
logical indicating if a frame (box )
should be drawn in the 1D case. Defaults to true when x has
dimnames coerce-able to numbers.
...
further graphical arguments, see plot.default .
axes = FALSE is accepted.

plot.factor , the plot method for factors.
Examples
## 1-d tables
(Poiss.tab <- table(N = stats::rpois(200, lambda = 5)))
plot(Poiss.tab, main = "plot(table(rpois(200, lambda = 5)))")
plot(table(state.division))
## 4-D :
plot(Titanic, main ="plot(Titanic, main= *)")
