问题
I use the Anaconda Python distribution on Ubuntu linux and would like to use R magics in IPython notebooks. Is there a way to install rpy2 with the conda distribution and use my current default R installation at /usr/bin/R? My goal is to keep the current R installation as is without installing R or other R packages via conda.
This response to a related question suggests using a recipe for doing so on mac, but doesn't work for me:
conda skeleton pypi rpy2
conda build rpy2
conda install rpy2 --use-local
The build command yields the follow error:
Error: No packages found in current linux-64 channels matching: singledispatch
I can install singledispatch via binstar:
conda install -c https://conda.binstar.org/asmeurer singledispatch
conda list | grep "singledispatch"
singledispatch 3.4.0.3 py27_1
But I get the same error regarding there being no packages found in current linux-64 channels.

I had a similar issue with the package not installing in the proper place, I would recommend instead using apt instead of conda
sudo apt install python-rpy2
edit: * note official support for rpy2 has been discontinued for 2.7 *
