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~.,
HI,
May be this helps:
t2 <- table(c(10,11,12,13))
t1 <-table(c(1,1,2,4,5))
t <- c(t1,t2)
tapply(t,sort(as.numeric(names(t))),sum)
A.K.

Ideally I would like
t1 <- table(x1)
t2 <- table(x2)

Not directly. Something could probably be fashioned using it and
as.data.frame on the result of table(), but merge doesn't sum values.

For count data, which were my main concern, it looks as if tabulate with
nbins will work. I'm not sure how this works with a cross-classifying
factor, which I will also need.
Can anyone recommend a good way to add tables?
Ideally I would like
t1 <- table(x1)
t2 <- table(x2)
t1+t2
It t1 and t2 have the same levels this works fine, but I need something
that will work even if they differ, e.g.,
> t1
1 2 4 5
2 1 1 1
> t2 <- table(c(10, 11, 12, 13))
> t1+t2 # apparen
