I am wondering if there is any function in R that is similar to the "scan" function in SAS. I have a data.frame which has two columns as the following: one two 1 2 3 4 5 6
I used the "paste" function to create the third column: three <- paste(one,'-',two,sep="") so the data.frame is like this now: one two three 1 2 1-2 3 4 3-4 5 6 5-6 My question is, is there any function in R that can do the opposite thing to what "paste" does? suppose I only have the third column "three" now, and I want to get the first and second columns. If in SAS, I can do the following: one = scan(three,1,'-') two = scan(three,-1,'-') How can I do this in R? thank you, karena -- View this message in context: http://r.789695.n4.nabble.com/any-function-in-R-similar-to-the-scan-function-in-SAS-tp2131264p2131264.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.
