[R] Installing pre-compiled R in Linux

Thu Oct 8 02:18:29 CEST 2015

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.

Thanks & Regards
Sasi
