I have compiled a notebook from this link

Replace the actual installation location for R on your machine. I have just tested it on Win10 with R 3.6.1 in Version 12.1.1 and it works.

You can download the notebook attached.


InstallR[] works in version 12, but not in Version 12.1

In[1]:= $Version

Out[1]= "12.0.0 for Microsoft Windows (64-bit) (April 6, 2019)"

In[2]:= Needs["RLink`"]

In[3]:= InstallR[]

In[4]:= REvaluate["sample(1:100,10)"]

Out[4]= {76, 84, 1, 79, 97, 16, 65, 73, 81, 98}

InstallR[] began by downloading from the Wolfram server, but then failed for me, too, with Mathematica 12.1.1 under Windows 10 Pro (actually, running as a virtual machine via Parallels Desktop for Mac" under macOS Catalina 10.15.6).

It works, though, directly in the Mac version of Mathematica 12.1.1 .
