Using grep
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
