What about providing a new function rvle.source(package="mypackage") ?

[rtrepos]

R scripts are often dedicated to specific models (or vle packages) and it seems difficult to share code (provide high level functions) into the rvle package that should be kept simple I think.

A solution could be to provide R packages to models or vle packages, but it requires lot of technical check due to the dev of R packages.

A simple way could be to provide R scripts into eg. mypackage/R/export.R
and to provide a function in rvle (eg rvle.source) that simply source this file.
