I have a data.frame as follows: v1 v2 v3 v4 v5.....v100 1 1 0 0 1 2 2 1 2 1 0 1 1 1 1 2 1 0 . . . . . . . . . . . . 1 2 2 1 1 0
so for this data set, what I wanna do is to replace all the '2' with '1', how can I do it in an efficient way? thank you, karena -- View this message in context: http://r.789695.n4.nabble.com/a-question-about-replacing-the-value-in-the-data-frame-tp2532010p2532010.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.
