Dear all, Sorry to bother you, but I didn't find the solution in the R-help archive. I would like to change the thickness of stripes inside the barplot. Is there any solution to do that when using the barplot() fuction and the density option ? Or is there any other function ? Thanks very much for your help. Best regards. Gael.
