The objective should be that creating a package is as easy as this:

   f <- function()1; g <- function()2; d <- 3; e <- 4:5    package.skeleton(list=c("f","g","d","e"), name="AnExample")    library(AnExample)
   f()    

which means that the package needs to be inserted where library will find it. It should not be necessary to have an understanding of this.
