Hello,
I am trying to find a function name in a string that expresses a
functional form :
s = blabla...S(var)...blabla
I would like to detect the pattern S(*) in s.
I am no guru at regular expressions. Just tried :
grep(S(.*),c(S(a),CSP))
[1] 1 2
I expected the pattern to be retrieved

Parnetheses have special meaning so they must be escaped or
specify a character class of 1:
grep(S\\(.*\\),c(S(a),CSP))
[1] 1
grep(S[(].*[)],c(S(a),CSP))
[1] 1
