[R] For MacBook, best way to do R?

[Mitchell Maltenfort]

I'm getting a MacBook and I'd like to stick with OS X rather than
convert it to Linux just yet.

However, my main concern is having decent performance.

What's my best option:

*use the existing binary for R?

*compile R fresh under OS X?

* install Linux and run R under that?

Does anyone have any recent experience they can share?  Thanks!
