Well, not quite *all* the functions. If the package has a namespace, then you won't be able to see the functions that are sealed in the namespace using ls(). There may be a way to spit out all the functions from within R including those in the namespace, but I don't know how. The only way I know to get everything is to get the source package and troll through the files in the packagename/R directory. Jim -- James W. MacDonald, M.S.
