danpos2 error messages

Question

[ChIP-Tease]

Hello everybody,

i try to run danpos2, but only get error messages i cannot solve on my own.

$ danpos.py
cannot find system Renviron
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rpy2/rinterface/__init__.py:186: RRuntimeWarning: Error in identical(env, as.environment(i)) :

    __show = rpy2.rinterface.baseenv.get("show")
LookupError: 'show' not found

I tried to remove rpy2 and reinstall it again, but installing does not work at all due to some compilation problem: i asked for help in another post:

https://stackoverflow.com/questions/44331415/pip-install-rpy2-does-not-work-and-produces-error-message-concening-compilation

I though the error messages might mean i need to install wigs or functions or rpy2, but I'm not really into python and 'pip install wigs' resulted in the announcement that there is nothing like a wigs package. I'd be happy if someone could please tell me how i can handle these error messages. Do i have to install packages or may it be a wrong version of a program? I use Python 2.7.8 Thanks a lot

At least i found out that all these errors occur because rpy2 is missing. But i still don't know how to fix this.

OK, i could fix the rpy2 problem, now other problems occur.

How did you install rpy2? I've found the most convenient method is to use anaconda python and use conda to install R and rpy2.

[ChIP-Tease]

Before I used $pip install rpy2.

Thanks a lot for your hint!!! Now I installed anaconda2 for the command line, used $conda install rpy2, which installed rpy2 and i guess dependencies and now danpos works. I didn't even had to change anything about R. Thanks a lot again :)
