Hello again, Let say I have following vector:
set.seed(1) Vec <- sample(LETTERS[1:5], 10, replace = TRUE) Vec Now with each repeated letter, I like to add suffix programatically. Therefore I want to get following vector: c("B", "B1", "C", "E", "B2", "E1", "E2", "D", "D1", "A") Can somebody tell me how to achieve that?
