The only way I know to do this is to use a finalizer, as we don't run .Last.lib on shutdown. (That's how RODBC does it.) Now, as I recall this cannot be done from reg.finalizer, only from the C-level R_RegisterCFinalizerEx, which has an optional argument to ensure that the finalizer is run 'onexit'. (I have never understood why we have that restriction, nor why reg.finalizer is primitive and not .Internal.) -- Brian D.
