[R] Clustered boxplots

[Chuck Cleland]

You might consider bwplot() in the lattice package instead.  For example:

mydata <- data.frame(Y = rnorm(3*1000),
                      INDFACT =rep(c("A", "B", "C"), each=1000),
                      CLUSFACT=factor(rep(c("M","F"), 1500)))

library(lattice)
trellis.device(new=FALSE, col=FALSE)

bwplot(Y ~ INDFACT | CLUSFACT, data=mydata, layout=c(2,1))
