Hi Rosario,
If you already have your percentages, the barplot function will display
them like most people expect an histogram to look by setting space=0.
See the "names.arg" argument to have the names of your nominal variables
on the x axis. I'm not sure exactly what you mean by wanting 2
categories below 0. If these are negative percentages, the barplot
function will automatically handle them.
