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.
