This works very well--thanks so much. By way of extension: how would one extract elements from the result object?
For example: thing<=apply(Dtb[,3:10], 2, function(x) wilcox.test(x~Dtb$Group)) summary(thing)$p.value Does not provide a list of p-values as it would in a regression object. Ideally, I would like to be able to extract the W score and p-value by A,B,C,... Any ideas greatly appreciated! -- View this message in context: http://r.789695.n4.nabble.com/Mann-Whitney-by-group-tp4635618p4636055.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
