bar plot issues

Hi Uwe!

2011/10/20 Uwe Ligges<ligges at statistik.tu-dortmund.de>:

arrange it outside by, e.g. increasing the size of margins (see argument
"mar" in ?par) and place a separate legend (see ?legend) into the margins
(see xps argument in ?par).

I could not find 'xps',  do you mean 'xpd'?

This is what I have so far:

par(mar=c(5.1,4.1,4.1,12.1))
barplot(t(file.codes), beside = FALSE, legend = FALSE, main="test stacked bar plot", xlab="documents", ylab="number of codes", col=rainbow(ncol(file.codes)), names.arg = rep(NA, nrow(file.codes)))

danke,
Henri-Paul
