I need to apply some function on two lists. I have to use the index to do as shown above. But I feel more natural to refer to the lists without using the index (using the syntax of something like, lapply(x,y, function(i,j){....})). I'm wondering if there is such a thing in R? Or there are some other ways better than the example at the very beginning? ______________________________________________ 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.
