Dear list, I have a vector of letter strings as follow:
> LETTERS[c(1:7,9,15,18:25)] [1] "A" "B" "C" "D" "E" "F" "G" "I" "O" "R" "S" "T" "U" "V" "W" "X" "Y" I need to find sequences of length 11, which are made from all possible permutations with repetition (not the unique ones) of the letter string A with the other strings, for example AAAAAAAAAAB, AAAAAAAAAABC, AAAAAAAAACB, AABAAAAAAAB. A can be repeated 1-11 times in the sequence. Is there a way to do this in R? Any help would be much appreciated. Best regards, Yen [[alternative HTML version deleted]]
