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)))")

data(state)
plot(table(state.division))

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