Thanks a lot Mike. The Linux distribution we use is "Red Hat Enterprise Linux Server release 6.2". Also, couple of clarifications, 1. Do we have a R package compatibility matrix against the Linux kernel version? Or for the Red Hat Linux with kernel version 2.6.32-279, do you have any suggestion/recommendation on R package to be used? 2. If we need to use Rscripts in embedded systems such as routers and switches, do we need to install the complete R package in the system also? Or just libR.so and Rscript should be ok? Thanks again Mike.

I don't think kernel compatibility is a significant issue for most applications. I can say for certain that I update the kernels on my linux boxes without having to reinstall R. There *are* R packages for RHEL and friends. Have a look at: https://cran.r-project.org/bin/linux/redhat/README Note that there's a bit of fiddling required, but I don't think it's particularly complicated. It's usually not particularly difficult to install R from source. If you prefer to do that, have a look at: https://cran.r-project.org/doc/manuals/r-release/R-admin.html Also, you don't specify your requirements, but don't overlook the possibility of installing a virtual machine on your RHEL server. (It's somewhat easier to get an R package for Fedora or Ubuntu than for RHEL, for instance.) I don't know the answer to your question about embedded systems. I would think R would not be a great choice for an embedded system, but I don't know what your requirements are. -- Mike On Tue, Oct 6, 2015 at 9:42 PM, Sasikumar Kandhasamy <ckmsasi at gmail.com> wrote:> Thanks a lot Mike.

The Linux distribution we use is "Red Hat Enterprise >> Linux Server release 6.2".On RHEL and CentOS the easiest and most reliable way to get R and R packages is via EPEL. Simply add the EPEL repositories and from there on you can install R and R packages as you would do on Fedora.
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.
