I've read a number of examples on doing a multiple bar plot, but cant seem
to grasp
how they work or how to get my data into the proper form.

I have two  variable holding the same factor

The variables were created using a cut command, The following simulates that

A <- 1:100
B <- 1:100
 A[30:60] <- 43
 Acut <- cut(A,breaks=c(0,10,45,120),labels=c("low","med","high"))
 Bcut <- cut(B,breaks=c(0,10,45,120),labels=c("low","med","high"))

What I want to do is create a barplot with  3 groups of side by side bars

group 1, = "low" and the two bars would be the count for Acut, and the count
for Bcut
group 2 = "med" and the two bars again would be the counts for  this factor
level in Acut and Bcut
group 3 = high  and like the above two.
