Hi, I have a data.frame as following: var1 var2 1 ab_c_(ok) 2 okf789(db)_c 3 jojfiod(90).gt 4 "ij"_(78)__op 5 (iojfodjfo)_ab
what I want is to create a new variable called "var3". the value of var3 is the content in the Parentheses. so var3 would be: var3 ok db 90 78 iojfodjfo how to do this? thanks, karena -- View this message in context: http://r.789695.n4.nabble.com/question-about-string-handling-tp2289178p2289178.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org 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.
