R: Mosaic Plots

PlotMosaic

R Documentation

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.

Details

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

Value

list with the midpoints of the rectangles
