I'll double check. I've done this before but I recall it was always a bit 
messy. Do we prefer using yum or is installing from source also a possbility? 

What centos version will we use? I just worked up a quick server from digital 
ocean with centos 7 and this seems to work just fine: 

```
[root@servy-server ~]# yum install -y epel-release
[root@servy-server ~]# yum update -y
[root@servy-server ~]# yum install -y R
[root@servy-server ~]# R

R version 3.2.0 (2015-04-16) -- "Full of Ingredients"
Copyright (C) 2015 The R Foundation for Statistical Computing
Platform: x86_64-redhat-linux-gnu (64-bit)

>
```

The downside of YUM is that it is not always up to date (the latest version is 
3.2.1). This version of R should allow almost all Rstudio packages to just go 
and work out of the box. 

Depending of which version of CentOS we use, getting epel might be a problem. 
In the past this  made it more practical to just go and install R from source. 
This is not too terrible, it can be done this way: 

```
[root@servy-server ~]# wget http://cran.rstudio.com/src/base/R-3/R-3.2.1.tar.gz
[root@servy-server ~]# tar xvf R-3.2.1.tar.gz
[root@servy-server ~]# cd R-3.2.1
[root@servy-server ~]# ./configure --prefix=$HOME/R-3.2 --with-readline=no 
--with-x=no
[root@servy-server ~]# make && make install
```

The main downside is that this will take a fair amount of time.
