[R] Sampling letters

I have a binary matrix of size N x 300. I then create the following: > set.seed(1234) > (key_file <- sample(letters[1:4], 300, replace=TRUE)) [1] "a" "c" "c" "c" "d" "c" "a" "a" "c" "c" "c" "c" "b" "d" "b" "d" "b" "b" "a" "a" "b" "b" "a" [24] "a" "a" "d" "c" "d" "d" "a" "b" "b" "b" "c" "a" "d"
