Also, there is the possibility to use scan() on a text connection > string<-"1,1,2,3,5,8" > v <- scan(tc <- textConnection(string), sep=","); close(tc) Read 6 items > v [1] 1 1 2 3 5 8 In r-devel, this works too: > v <- scan(text=string, sep=",") -- Peter Dalgaard Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.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.
