Hello, This one will do it.
x <- 1:4 y <- 2:5 t1 <- table(x) t2 <- table(y) (xy <- c(rep(names(t1), t1), rep(names(t2), t2))) table(xy) Hope this helps, Rui Barradas Em 13-08-2012 19:25, Francois Pepin escreveu:
Hi everyone, Is there an easy way to combine the counts from table()? Let's say that I have: x<-1:4 y<-2:5 I want to replicate: table(c(x,y)) using only table(x) and table(y) as input. The reason is that it's cumbersome to carry all the values around when all I care about are the counts. The actual situation has about a billion counts over ~150 categories. I know there's got to be a number of ways of doing things (plyr comes to mind), but I can't seem to find how to accomplish it.
