[R] Installing pre-compiled R in Linux

[Sasikumar Kandhasamy]

Thanks Mike. From source, i am able to compile and use R in my red hat
linux box. I was trying to get hands on using R in linux box before trying
R on the embedded box.

My requirement is to run R (R scripts) on my embedded box which has
customized debian linux (kernel version 2.6.32) in batch mode without GUI
support. The embedded box have multi-core MIPS processor with nearly 30GB
RAM. I hope hardware resources on the embedded box shouldn't be an issue to
run R (correct me if i am wrong), but linux version running here is an
customized one with limited supporting services such as light weight shell
etc.

Given this, do i need to cross compile R package for my embedded box or i
can directly install the debian MIPS version of R package. But there is no
apt-get or other installer in the embedded box.


Regards
Sasi
