Hi all

(I'm sure this question has been asked before, but I cant find it).

If I have two character vectors:

> x <- c("aaa","bbb","ccc")
> y <- c("1","2","3")

How can I get the cartesian product of the string values?

> expand.grid(x,y)

Gives me a data frame with separate columns...however, I cant seem to get *apply to paste the column values together.

Thanks
Rory
