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?

RuntimeError: R_HOME not defined.
The R home directory is the top-level directory of the R installation being run. The R home directory is often referred to as R_HOME , and is the value of an environment variable of that name in an R session. It can be found outside an R session by R RHOME .
rpy2 is an interface to R running embedded in a Python process.
Open a cmd window (as Administrator) in the . whl's download dir. Set R_USER env var to current username: set R_USER=%USERNAME% python -m pip install rpy2‑2.9.
I confirm this issue is related to R_HOME
variable not defined.
In my opinion, all of these issues are caused because the developers of rpy2
package haven't documented properly the requirements of their software:
R
R_HOME
system variableR_HOME\bin
to the PATH
, in order to execute R
from python
R_HOME\bin\x64
to the PATH
, in order to load R.dll
tzlocal
