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.

Hi, Sasi. Yes, I think that getting familiar with R in a "friendly" context before dealing with your embedded system is a good idea. Note that the non-GUI part of R is more or less identical across platforms. Hence, you could experiment with it on a Macbook, a Surface tablet, etc., etc., if you're just seeking to get established in R. The hardware configuration of your embedded system seems reasonable, but again, I don't know what your run-time requirements will be. Note in particular that R likes to have objects resident in memory, so if you're trying to process a 40GB data file on your embedded system, you're probably out of luck. I would certainly start by trying to install the Debian package for R. Even if you don't have apt-get, I would think you'd at least have the "dpkg" utility: https://www.debian.org/doc/manuals/debian-faq/ch-pkgtools.en.html If so, you could use that to install R (provided you have managed to download the appropriate <*.deb> package for R).

Thanks a lot Mike & others for the valuable input. I was wrong on debian linux on the embedded box, it is monta vista embedded linux. I hope, there is no R core package available for monta vista distribution and i may need to cross compile from R source. Please correct me if i am wrong.

There is a manual for compiling and installing R. There is also a mailing list
(described in the Posting Guide) called R-devel where topics like compiling R
are actually on topic, unlike here. If you have to cross-compile then you
probably have a bit more work ahead of you than most users would have, so be
prepared to roll up your sleeves and get familiar with the innards of R so you
can decide exactly which features you need. I have not heard of anyone rolling R
into an embedded system, but this list would not be the place to hear about it
so that probably doesn't mean much.

Sure Jeff, thanks a lot for the references. Will explore more and will also try to contact R-devel list for further help on cross compile. Thanks again to all for the quick responses.
