plot.table: 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 table
plot(x, type = "h", ylim = c(0, max(x)), lwd = 2,
     xlab = NULL, ylab = NULL, frame.plot = is.num, …)
# S3 method for table
points(x, y = NULL, type = "h", lwd = 2, …)
# S3 method for 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= *)")
