[R] Bar chart

[Leonardo Lami]

Hi,
I'd like plot a bar graphic of a array.
I'd like to have the values of the single columns as juxtaposed bars (like in 
"barplot" with beside=TRUE) and I'd like to have the values of the single 
columns expressed  like percentage of the sum of the coloumn.
In this way all the bars are composed by the sum of the percentage of the 
values of a coloumn (with different colors) and all they have 100% value. 

Thanks
Leonardo Lami
