I am quite new to R, and pretty much used to python. I am not so comfortable writing R code. I am looking for python interface to R, which lets me use R packages in pythonic way.
I have done google research and found few packages which can do that:
But not sure which one is better ? Which has more contributers and more actively used ?
Please note my main requirement is pythonic way for accessing R packages.
As pointed out by @lgautier, there is already another answer on this subject. I leave my answer here as it adds the experience of approaching R as a novice, knowing Python first.
I use both Python and R and sympathise with your need as a newcomer to R.
Since any answer you get will be subjective, I summarise a few points from my experience:
My advice:
Once you know both, then you will do magic with rpy2 without the horrors of cross-language debugging.

This answer has proved popular and so I thought it would be useful to point out two more recent resources:
The triplet R, Rserve, and pyRserve allows the building up of a network bridge from Python to R: Now R-functions can be called from Python as if they were implemented in Python, and even complete R scripts can be executed through this connection.
rmagic
in IPython/Jupyter
greatly easing the work of producing reproducible research and notebooks that combine both languages.
