[R] Reducing of car package when loading

[Brian Bolt]

I am not sure what functions I use in car actually.  I am dependent on the drc package which imports "car".  The main drc function I use is "drm", along with "LL.4"

To be clear, I am not just asking about the car package but reducing memory dependence in general.  Can I force the R package loader to only load functions from packages that I am dependent on? Is there a way to not load all of the datasets?
