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 only in the first string, so obviously this is not correct. Any idea ? Thank you very much in advance, Yvonnick Noel, PhD U. of Rennes 2 France ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
