PlotMosaic: Mosaic Plots

Description

Plots a mosaic on the current graphics device.

Usage

PlotMosaic(x, main = deparse(substitute(x)), horiz = TRUE, cols = NULL, off = 0.02, mar = NULL, xlab = NULL, ylab = NULL, cex = par("cex"), las = 2, ...)

Arguments

x

a contingency table in array form, with optional category labels specified in the dimnames(x) attribute. The table is best created by the table() command. So far only 2-way tables are allowed.

main

character string for the mosaic title.

horiz

logical, defining the orientation of the mosaicplot. TRUE (default) makes a horizontal plot.

cols

the colors of the plot.

off

the offset between the rectangles. Default is 0.02.

mar

the margin for the plot.

xlab, ylab

x- and y-axis labels used for the plot; by default, the first and second element of names(dimnames(X)) (i.e., the name of the first and second variable in X).

cex

numeric character expansion factor; multiplied by par("cex") yields the final character size. NULL and NA are equivalent to 1.0.

las

the style of axis labels. 0 - parallel to the axis, 1 - horizontal, 2 - perpendicular, 3 - vertical.

...

additional arguments are passed to the text function.

Value

Details

The reason for this function to exist are the unsatisfying labels in base mosaicplot.
