OSError: cannot load library 'C:\Program Files\R\R-4.0.2\bin\x64\R.dll': error 0x7e

Question

I am trying to import the rpy2 library into a Jupyter Notebook but I cannot get past this error.

The PATH \'C:\\Program Files\\R\\R-4.0.2\\bin\\x64\' has been added.<

Answer 1

Here is my working solution:

import os
os.environ["R_HOME"] = r"D:\Install\R\R-3.6.1"
os.environ["PATH"]   = r"D:\Install\R\R-3.6.1\bin\x64" + ";" + os.environ["PATH"]
import rpy2
from rpy2.robjects import pandas2ri, packages
pandas2ri.activate()
stats = packages.importr('stats')

Answer 2

I found a solution here.

Adding the PATH

C:\Users\username\Anaconda2;C:\Users\username\Anaconda2\Scripts;C:\Users\username\Anaconda2\Library\bin;C:\Users\username\Anaconda2\Library\mingw-w64\lib;C:\Users\username\Anaconda2\Library\mingw-w64\bin

and subsequently restarting Anaconda fixed the issue.
