[R] Barplot - Can't figure it out

[T Petersen]

Almost. Catagories aren't stacked - I would like to see that x has 2 
instances of "1" while y has 1 instance of "1". What's more, there are 
now TWO distinct barplots - the left one shows x, while the right one 
shows y. I could live with that, but what I'd ideally want is to have x 
and y beside each other for EACH catagory - so for catagory "1" you 
could see taht there are more x's than y's (two x's versus one y). But 
thanks for the help
