Re: [R] adding tables
How about this: t2 - table(c(10,11,12,13)) t1 -table(c(1,1,2,4,5)) t12-(rbind(as.data.frame(t1),as.data.frame(t2))) xtabs(Freq~.,t12) it works for overlapping tables t2 - table(c(10,11,12,13,1,2)) t1 -table(c(1,1,2,4,5,11,12)) t12-(rbind(as.data.frame(t1),as.data.frame(t2))) xtabs(Freq~.,t12) and it will work for two-dimensional tables as well: t2 - table(c(10,11,12,13),letters[rep(1:2,each=2)]) t1 -table(c(1,1,2,4,5),letters[rep(c(1,3),length.out=5)]) t12a-(rbind(as.data.frame(t1),as.data.frame(t2))) xtabs(Freq~.,t12a) cheers.

It's possible the factor may have missing values in some tabulations as well. By using the levels argument to factor one can ensure that all possible levels are present. Then table() will do the right thing. An example with numbers: t1 - factor(c(3, 2), levels=1:5) t1 [1] 3 2 Levels: 1 2 3 4 5 table(t1) t1 1 2 3 4 5 0 1 1 0 0 This works in arbitrary dimensions.
