Dear all, I have three vectors "x<-1:n", "y<-1:m" and "z<-2:(n+m)". I need to find all combinations of "x" and "y" that add up a given value of "z", e.g., for "z==3" the combinations will be "list(c(1,2),c(2,1))".
Thanks in advance for your help. ______________________________________________ [email protected] 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.
