[R] install R-devel from R 3.1 to R 3.2 kubuntu

[Karim Mezhoud]

Dear all,
I found some threads about compiling r-devel source and installing process
but I need some clarifications.
1. Is it better to uninstall R 3.1 before installing R-devel?
2. I have multiples library directories, R-devel will use these libpaths?
> .libpaths()
[1] "/home/mezhoud/R/x86_64-pc-linux-gnu-library/3.1"
[2] "/usr/local/lib/R/site-library"
[3] "/usr/lib/R/site-library"
[4] "/usr/lib/R/library

3. is there a complete tutorial for R-devel installing in GNU/Linux OS?

Thanks,
Karim
