[R] Barplot - Can't figure it out

[T Petersen]

Hi,

I have two catagorical vectors like this;

x = c(1, 2, 4, 2, 1)
y = c(2, 4, 2 ,4, 1)

I want to set up a barplot with the catagories 1-4 horizontally  and 
number of occurances vertically for each vector x,y. I've tried

boxplot(table(x,y), beside=T)

and

boxplot(c(x,y), beside=T)

among others, but can't get it to work...Any ideas? I'd apppreciate any help
