Hello,
I have a column with a bunch of letters. I would like to keep some of these
letters (A,C,D,L) and turn the rest into 'X'.
I have tried using ifelse with '|' in between the argument but it didn't work
nor did 4 separate ifelse statements.
Example, I currently have:
Letters A B C D E
I would like to have:
Letters A X C D X
Thank you

try:
let = sample(LETTERS[1:5],100,replace=TRUE)
let
let1 = ifelse(let %in% c('A','C','D'),let,'X')
let1
