Maybe said before, sorry I have not read all threads. I have read chap. 1 available online. You say your PC has 2mg. RAM, and a Mac can use all 4mg. of RAM if installed. I suppose you mean 2 GBytes RAM. A Mac can use 4, 8, 12, 16 GB of RAM if available and if O.S. is snow leopard. You need 64 bit R for handling >3.5GB objects, and these are only freely available for Linux 64 bit OS's and for Mac Snow Leopard (10.6). With these you can use up to the installed RAM.

Re: tiny comment on intro
This is definately a typo. I meant to indicate that I was using a PC with 2 Gb of RAM and a Mac with 4 Gb of RAM.

You are absolutely right. I did not mean to imply that R could use all of this memory. I was just giving a ballpark example of the problem size that I work with on my own machines. In the Appendix, I will talk specifically about R limitations and methods for overcoming them.

Thanks for catching this! I will clarify this and make the corrections.

Sincerely,

Rob

Gb stands for gigabits. You want to say gigabytes, which is GB.
