rpy2 import is not working

Question

I get an error when I try to import rpy2. Here is the code and error.

>>> import pandas.rpy.common
Traceback (most recent call last):  

File \"C:\\PF\         


        

Answer 1

That looks like a pandas interface to rpy2. Separately, you also need rpy2 installed on your system. I don't have rpy2, so it was easy for me to check this:

In [1]: import pandas.rpy.common
(...)
ImportError: No module named rpy2.robjects.packages


In [2]: import rpy2
(...)
ImportError: No module named rpy2

I installed it using pip:

$ pip install rpy2

In [1]: import pandas.rpy.common

It works! It import rpy2 works for you, but import pandas.rpy.common does not then the problem might be more subtle.
