Hi all, I'm trying to rank a couple of factors by a variable and a weight of the variable in each occurrence (some samples are bigger than others).
input = data.frame( alfa = rnorm(5000), weight = rnorm(5000,-50000,100000), tag1 = sample(c("a","b","c","d"),5000,replace=TRUE), tag2 = sample(c("i","j","k"),5000,replace=TRUE) ) alfa are the observations, each of which has a weight, and tag1 and tag2 are the factors. The idea would be to have a ranking of tag1, tag2, and a combination of both. There must be a way to do that with ave() or sort() but I haven't found how. Thanks in advance, Albert. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
