There's also http://www.stat.uiowa.edu/~luke/R/gengcnotes.html, but it's more 
about the internals, hence may have changed more, and also, I don't know, how 
old it is. Anyway, you're asking because of concern for limiting memory 
allocation?

As far as I can see, the information on that is still correct. I've given 
mem.limits() a short test, and it seems to work fine. So we could/should 
provide an interface to that function to limit memory usage. However, I don't 
think it's an urgent issue for now. Users dealing with huge data or 
excessively memory-hungry tests can be expected to read up on mem.limits() 
for a while longer (and before looking about a corresponding setting in the 
GUI, they'd need to be aware of the issue, anyway).

Or did you have something else / more specific in mind?

Thomas
