question about boxplot
You can also set axes=FALSE as in
boxplot( p.prop ~ R + bins, axes=FALSE )
and then add your own labels with axis(). the argument 'at' for axis() in the
case of boxplots are usually integers going from 1 to # of groups, though I
don't know specifically for your crossed factors.
For rotated names, you probably want to set axis(#arguments#,labels=FALSE)
and then use text() with 'srt' (don't forget to use xpd=TRUE in text()).
par("cxy") may help with positioning text relative to axis.
all the best,

boxplot( p.prop ~ R + bins ) This command makes nice boxplot for the factor "R" crossed with the factor "bins". I am having alot of trouble getting control of the labels on the X axis. I want to control it more by specifying what the labels are, controling the 'size' of those labels (by using cex), and then control the rotation of the character strings of those labels (by using srt or crt). There is a "names" argument to boxplot, but I haven't had much luck controlling what it prints, the size of the font, and the character rotation.
Would you consider an easy way out---an alternative with reasonable defaults? data(ToothGrowth) bwplot(dose ~ len | supp, ToothGrowth)
