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).
