Permutation with two vectors

Hi, can you please format your code as code? Also, it'll be helpful if you can make your question into a reprex:

Right now it is difficult for me to see what you want exactly since as I read it, you have 4 groups with money, not 3. But in general, you can take a look at purrr::cross:


purrr::cross2(letters[1:3], LETTERS[1:3]) %>%
  purrr::map_chr(purrr::lift(paste, sep = "."))
#> [1] "a.A" "b.A" "c.A" "a.B" "b.B" "c.B" "a.C" "b.C" "c.C"
