Well I am a little lost in your explanation maybe you could show us part of your variables. Anyway if rel is existence of relation > rel<-sample(0:1, 10, replace=T) and int is intensity of relation > int<-sample(1:5, 10, replace=T) whole <-int*rel [1] 2 1 5 2 5 0 4 4 0 2 Gives you 0 where there is no relation and numbers 1:5 showing intensity of relation change it to factor whole <-factor(whole) and chase levels levels(whole) <-rep(c("weak", "medium", "strong"), each=2) Regards Petr > Do you know any way to do so. > > Regards, > Niklas > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. ______________________________________________ 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.
