[R] Installing R and modules on Unix OS

[Vadlamani, Satish {FLNA}]

Hi:
I have a question about installing R (and modules) on a Unix system (AIX).
Can I just gunzip (or the equivalent) the installation files into my home directory or will I need someone with root access to install R? I am hoping that the answer is the former (I can unzip all files to a directory R that I create under my home directory and I can start using it).

Could you please help me with this and any other instructions to install R and modules when you do not have root access? Thanks.
