R Documentation

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.

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= *)")
