Answer 1

If you want to use Python with rpy2 but you also want to keep using your RStudio, don't forget to add RStudio to your path as well, or you'll get some path issues.

You can change your paths according to @user3758274:

Change Path for R computer-> property -> advanced and system setting -> environment variables in the user variable field add C:\Program Files\R\R-3.0.2\bin\x64 (my system is windows 64bit) to path

In the system variable field add two new variables

R_HOME    c:\program files\r\r-3.0.2

R_USER    C:\Users\"your user name"\Anaconda\Lib\site-packages\rpy2

But then add also RStudio to your R_USER system variable, so you'll get:

R_USER    C:\Program Files\RStudio\bin;C:\Users\"your user name"\Anaconda\Lib\site-packages\rpy2
