[R] helps on upgrading R in Mac OS

[Mao Jianfeng]

Dear R-helpers,

I intend to upgrade R in Mac OS with updated R version and updated Mac
OS version.

I think my Mac notebook is produced with Mac x86_64, darwin9.8.0. I
have updated my Mac OS to  Mac OS X version 10.6.5. But, when I
installed R 2.12.1, the "version" function still gave me information
that R is based on old Mac OS. I need to know how can I update R to
let it to fit for the updated Mac OS.

Could you please give me any direction on that? Thanks in advance.
