R help - Sep 2009 - how to add tables of different dimensions

Hi all!
I'm stuck with this "easy" problem. I have two tables  (a and b)
which i would like to add. table a looks like:
a
var1 var2
3      4 
and table b looks like:
b
var1
10
I would like this result: c<- a+b
c
var1 var2
13    4
Best regards Henrik K?llberg

Try this:

colSums(rbind(a, b[1:length(a)]), na.rm = TRUE)
