Hi, I have a vector A with (200, 201, 202, 203, 204, ... 210) and a vector B with (201, 204, 209). Now I would like to get the position in vector A matches with the entries in vector B So what I want to have is the following result: [1] 2 5 10
I tried the following: grep(B, A) grep(c(B), A) A <- as.character(A) B <- as.character(B) grep(B, A) grep(c(B), A) and several other combinations. But nothing is giving me the right result?! Does anyone know why?
