Create a squareplot alternative to a segmented barplot

Description

Create a squareplot as an alternative to a segmented barplot. Useful when the viewer is interested in exact counts in the categories. A squareplot is often used by the New York Times. A grid of squares is presented with each color representing a different category. The colors appear contiguously reading top to bottom, left to right. The colors segment the graph as a segmented bargraph, but the squares allow an interested reader to easily tally the counts.

Usage

squareplot(x, col = gray(seq(0.5, 1, length = length(x))),
border =NULL, nrows = ceiling(sqrt(sum(x))), ncols =
ceiling(sum(x)/nrows),
...)

Arguments

x	a vector of counts
col	a vector of colors
border	border color passed to polygon
nrows	number of rows
ncols	number of columns
...	passed to title

Value

Creates the graph, but has no return value.
