I agree with both of you on this. Currently the method that Uwe describes is a lot easier than creating a package, but I think the objective should be to make things almost as easy as Gabor describes. Not completely as easy: he's missing the step where the package is installed. I think we want to keep that (because the distinction between the source of a package and the installed copy of it is important), but it should be easier to install a new package than it is now, especially in Windows. So I'm suggesting that it would be nice to be able to do something like this: f <- function()1; g <- function()2; d <- 3; e <- 4:5 package.skeleton(list=c("f","g","d","e"), name="AnExample") install.packages("AnExample", build = TRUE) library(AnExample) f() but currently install.packages doesn't know how to build, and for most Windows users, a fairly substantial effort is necessary to obtain all the tools.
