There is a limit on windows, read the FAQ:
http://cran.r-project.org/bin/windows/base/rw-FAQ.html#There-seems-to-be-a-limit-on-the-memory-it-uses_0021

So either you use a (64bit) Linux with enough memory or you use
packages or a SQL solution that is able to deal with huge datasets.
(biglm for example)
