[R] bar plot issues

[Henri-Paul Indiogine]

Hi Uwe!  Thanks for the feedback.   However, now the graph does not
draw the y-axis nor labels and gives the following error message:

Error in barplot.default(t(file.codes), beside = FALSE, names.arg = NA,  :
  incorrect number of names

This is the R code now:

barplot(t(file.codes), beside = FALSE, names.arg=NA, legend = FALSE,
main="test stacked bar plot", xlab="documents", ylab="number of
codes", col=rainbow(ncol(file.codes)))


I have head(file.codes) at the bottom of this email.

Thanks,
HP
