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 “bar like”.

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, ...)

Arguments

`x`	a `table` (like) object.
`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` coerceable to numbers.
`...`	further graphical arguments, see `plot.default`.

Details

The current implementation (R 1.2) is somewhat experimental and will be improved and extended.

Examples

## 1-d tables
(Poiss.tab <- table(N = rpois(200, lam= 5)))
plot(Poiss.tab, main = "plot(table(rpois(200, lam=5)))")

plot(table(state.division))

## 4-D :
plot(Titanic, main ="plot(Titanic, main= *)")
