Hello fellow R-users,
Given are three vectors and the outcome would be all possible combinations in
combination with the paste() function.
For example:
x <- c(1:3)
y <- letters[1:3]
z <- LETTERS[1:3]
My result would thus be 18 names based on all possible combinations between
these vectors:
"1 a A" "1 a B", "1 a C", "1 b A", "1 b B", "1 b C", "1 c A", "1 c B", "1 c C",
etc.
To solve the issue above I would use:
paste(rep(x, each=9), rep(y, each=6), z)
This is a very straightforward example, but when I have vectors of different
sizes, it will be much more difficult (for me) to create this. Is there an
easier way to do this?
Many thanks in advance,
-- Stan
