Hi Paolo,

The file read might not be the issue. Both your code and my code produce identical R data frames on input.

Again, the code returns nothing. No errors except for the following at the very end.
> dev.off()
null device
1

This rather intrigues me. It almost seems a simple statement is missing. But no, barplot does the work. Is barplot failing silently somehow?

My environment is MS XP SP 3, R 2.81 and my R packages are up to date.

Also my R successfully runs the examples found in R's help(barplot). And I appreciate that you put in the statement to display.brewer(all) which nicely shows what we can use.

Thanks,
Jim
