OK. From previous experience I've found there are not many instructions on how to install rpy2 on Windows. I get that it's not officially supported but it's really not that hard. In a few steps I'll show what I did and maybe others can follow.

These instructions will most likely only work for Python 2.7+ and R 3.2+ but will probably work for R 3.0+. I am putting the paths that I've used on my system. Make sure to modify the paths accordingly:

First, make sure any previous rpy2 installations are UNINSTALLED before trying these steps (and obviously have R 3.2+ before installing).

1. Download the .whl file for r2py from here
2. Install the .whl file using pip install [put .whl filename here] (in the command line) from the directory where the file was downloaded
3. Append a path similar to C:\Program Files\R\R-3.2.0\bin to your PATH environment variable
4. Create a R_HOME system variable with a value similar to: C:\Program Files\R\R-3.2.0
5. Create a R_USER system variable with your user name
6. Create a R_LIBS_USER system variable with a path to the folder where external R packages are/will be installed.

That's it. Open up a command prompt and enter the command R. This should start an R session and display version information.

Now open up python and run this line to see if things worked out or not:

import rpy2.robjects as robjects 

Hopefully this helps.
