  I think you need to try to specify your needs a little bit
more carefully.  Here is a function that technically meets
your needs:

library("example_pkg")  ## to load the contributed package
myfunction <- function() {  ## function with no arguments
   foo()                    ## assuming the function "foo" is in the package
   list(matrix(nrow=2,ncol=2),matrix(nrow=3,ncol=3),matrix(nrow=4,ncol=4)
}

  But I suspect that doesn't really do what you need ...
