ERROR:root:Cell magic `%%R` not found

Question

I have python 3 env

installed rpy2 with

conda install -c r rpy2=2.8.5

load the cell magic in jupyter notebook with

%load_ext rmagic

when I try to use R block in notebook, it gives me the error

ERROR:root:Cell magic `%%R` not found.

Answer 1

In a terminal:

pip install rpy2

In a notebook:

%load_ext rpy2.ipython

Then you can use %%R:

%%R
var <- c(1, 2, 3)

Answer 2

This is a link to the best answer I have found to the problem given on this thread: R Notebook.

This link states that the error means that R is not configured in your DSS instance. You need to install R manually.

The commands given on the forum post are:

1. Install the R packages RJSONIO and HTTR in any R console.

2. Install the Python package rpy2:

   pip install rpy2

Afterward, they give the following link: configure R.

I hope this is helpful and well worded.
