Hi David, I found this blog post helpful. I had a similar situation where I was installing R 3.3 on CentOS 6, and I found these instructinos worked well: http://pj.freefaculty.org/blog/?p=315 The only problem I had is that the instructions as written do not allow for using the R installation with RStudio or RStudio Server. For this, I believe you need the -fPIC option when installing R (and maybe the libraries as well), but not certain about this.
