grep for strings
I am trying to find the function where I can search for a pattern in a
text string (I thought I could use grep for this but no :().
> x
[1] "abcdefghijkl"
I want to find the positions (i.e. equivalent of nchar) for "cd" and
in case there are multiple hits .. then the results as a array
Thank you.
