It was my understanding that R wasn't really the best thing for absolutely huge datasets. 17.5 million points would probably fall under the category of "absolutely huge." I'm on a little netbook right now (atom/R32) and it failed, but I'll try it on my macbookPro/R64 later and see if it's able to handle the size better.
With 24GB on a Mac with 64 bit R, I routinely work with objects that are, let's see... 3,969,086,272, ... after commas .... 4GB in size (about 4.5 million records with about 100 columns). Thank you Simon and all the others doing R core and Mac development. As far as I am concerned 64bit R _IS_ the best thing.
