Quantlet: plotmosaic
Description: Graphical Contingency Table

Usage: plotmosaic(inX {,inY})
Input:
inX n x 1 Vector, discrete.
inY n x 1 Vector, discrete.

Note:

Example:
library("plot")
library("stats")
x1 = #("one", "one", "one", "one", "one", "one", "one", "one")
x1 = x1 | #("two", "two", "two", "two", "two", "two", "three")
x1 = x1 | #("three", "three", "three")
y1 = #("one", "one", "two", "two", "three", "three", "four")
y1 = y1 | #("four", "one", "one", "one", "two", "two", "two")
y1 = y1 | #("one", "four", "four", "four")
plotmosaic(x1, y1)
x2 = #(1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3)
y2 = #(1, 1, 2, 2, 3, 3, 4, 4, 1, 1, 1, 2, 2, 2, 1, 4, 4, 4)
plotmosaic(x2, y2)

Result:
Both calls of plotmosaic() generate a mosaic plot of x and y.
Note how the different orderings (alphabetical) influence
the appearence of the plot.
