Stop packages and datasets to be loaded on startup.

So I gather that just setting R_DEFAULT_PACKAGES to NULL should be OK. But then, what is the rather complicated stuff in the autoload() function in littler.c for?

And concerning datasets, how do you avoid loading them?

Setting R_DEFAULT_PACKAGES to NULL makes sure that default packages are not loaded. Note that "datasets" are not loaded at all -- you can load the datasets package which will make them available, but they are not really "loaded". The minimal setup is simply

R_DEFAULT_PACKAGES=NULL R --vanilla

However, it's your responsibility to load any packages that your code needs in that case.

Cheers,
Simon
