histogram help

Hi,

I want to generate an histogram and plot on the y axis the percentage of a
categorical variable and on the x axis a nominal variable. I want to move
the origin to have 2 categories below 0. Hope somebody could help me.
Thanks.

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.
