Hi, Is there a way to create a list of all statistical test functions in base R? For example, there's t.test, ks.test, chisq.test, etc. I'd like to create a list of these test names because I keep looking for different tests but never know what's available. I'm thinking of a regular expression statement but I'm not sure how this would work for functions. Or is there a list already available? Any suggestions? Thanks, Walt ________________________ Walter R.

Any suggestions?Hello, Perhaps you could operate on function names. Maybe something like: funs <- getNamespaceExports("stats") funs[grep(".*test$", funs)] Regards, -- Marek Gagolewski, Ph.D. Systems Research Institute, Polish Academy of Sciences ul.
