HOME Error with rpy2
I know there are quite a few posts on getting up and running with rpy2 on windows 7 32 bit. I have referenced a good number of them and attempted their solutions, including the use of PypeR .
I dont explicitly have a R_HOME variable set in my path, but per this question, I confirmed that R is in my PATH (I can type R at the command line and get R to run) and even copied all of the files from the i386 folder to the parent bin folder.
My issue is pasted below. Any thoughts?
In [5]: from rpy2 import robjects

RuntimeError: R_HOME not defined.
With help from the comment above, I got moving in the proper direction. I created the R_HOME as a SYSTEM variable. That didn't work right away, as I was getting an R_USER not defined error.
To get everything the import above to work without error, I simply re-installed the rpy2 exectuable from here after defining the R_HOME. No errors.
In summary, key was o have R_HOME set PRIOR TO installing rpy2.
