The last thing done in the startup is to load the default packages, so 
only base is loaded when .First is run. memory.size is in utils, so you 
need utils::memory.size.  See ?Startup ....

HOWEVER, it would be better to use --max-mem-size as part of the shortcut 
or alias you use to start R since saved data is loaded before .First is 
run.
