Let me present to you my problem :
I have a character vector x and I would like to obtain the indices of the
this vector that yielded exactly a match.
For example, x=nom, pattern="b", I would to obtain 2 because "b" is on the
First program :
nom <- c("a","b","ab")
Then I try the option extended =FALSE (instead of TRUE by default) and I
obtain '2 3' a second time.
Please can you help me : How can I obtain only 2 in using the grep function
(without using the match function).
