Dear R users,

I have a simple problem I cannot solve, but I sure you can help.

I have two vector, let say

> tmp1 <- c("a", "a", "b", "c")
> tmp2 <- c("a", "a", "b", "c", "c", "d")

and I want to create a matrix of two column for which I have all the combinations of the same character, let say like this

> tmp3

     tmp1 tmp2
[1,] "a" "a"
[2,] "a" "a"
[3,] "a" "a"
[4,] "a" "a"
[5,] "b" "b"
[6,] "c" "c"
[7,] "c" "c"

how can I perform this task?

thank you!
