PlotMosaic(x, main = deparse(substitute(x)), horiz = TRUE, cols = NULL,
off = 0.02, mar = NULL, xlab = NULL, ylab = NULL)
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).
Value
list with the midpoints of the rectangles
Details
The reason for this function to exist are the unsatisfying labels in base mosaicplot.
