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?
Thanks and regards,
