Dear all, I'm looking for a function comparable to switch, to categorize a continuous variable in a few levels. Off course that can be done with a series of ifelse statements, but that looks rather clumsy. I looked at switch, but couldn't figure out how to use it for this. I guess that's not possible, as it only works with characters or integers, not with intervals.
Basically, I'm looking for a clean way to do : test <- runif(10,1,100) testFunc <-function(x){ x <- ifelse(test<10,"lowest", ifelse(10<=test & test <50,"low", ifelse(50<=test & test <90,"high", ifelse(90<=test & test<100,"highest",NA) ) ) ) return(as.factor(x)) } testFunc(test) Thank you in advance ______________________________________________ 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.
