You could look at the reshape package, using sum as the aggregate function.

I found a half decent solution to this, output the plots then combine

I think you can find your answer if you study this part of the
documentation for ifelse:
Details:
If yes or no are too short, their elements are recycled. yes will be
evaluated if and only if any element of test is true, and analogously
for no.
Also, consider this call:
