[R] Looking for position of character in a string

Hi all, I would like to check if a string contains "." in it. If yes, I would like to know the position of "." in the string. Eg: X<-"NM1236.3" In above example, "." is at position 7. I tried functions grep() and match(). It seems they couldn't detect ".". Thanks in advance for your help, Sit
