Dear Sirs I can't try the package sets because I have a old mac system. Package sets needs R = 2.6. I need to group some variables into a set of new variables defined by a particular modality:
Example: my.df = data.frame(var1=c(1,2,2,1,2,2,1,2), var2=c(2,2,1,1,2,2,1,1), var3=c(1,2,2,1,1,1,1,2), var4=c(1,1,1,1,2,1,2,1)) I'm looking for a way to compute set1 and set2? set1 = c(5,4) % (var1, var2) modality = 2 set2=c(3,2) % (var3, var4) modality = 2 Can you help me, please? Thanks a lot jorge ______________________________________________ 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.
