Re: [R] NPMC

Yes I had a data.frame but did not named the categorical variable "class" and the numerical one "var". It is working now. However I would like to do a comparison with several classes and variables. Is there a way of doing this? Or do I have to do a Wilcox.test for every variable? Thanks Marie. -
