On the Hub Worker node(s):

Python and R can be downloaded and installed separately* and it is also possible to use the Anaconda system.
Download and run the anaconda sh file.
Check the version: conda info

Install R: conda install r-base
(/opt/anaconda/bin/R now exists)
PROC R also requires: conda install r-jsonlite

No need to install Python ... it is already present in Anaconda
(/opt/anaconda/python)
PROC PYTHON also requires: numpy and pandas (python3 -m pip3 install numpy)

Add the following settings to <strong><span style="font-family: courier new, courier;">etc/nomad_plugin.yam</span></strong>l: (Note: not _custom!)

env:
 PYTHONHOME: /opt/anaconda3
 R_HOME: /opt/anaconda3/lib/R

hubctl service restart

note: If not using Anaconda then python is probably installed into the operating system so use:

env:
   PYTHONHOME: /usr
   R_HOME: /usr

note: In some cases we have needed to add a specific setting for the Python library:

  PYTHONLIB: /opt/anaconda3/lib/libpython3.8.so

* To install R alone you may use "yum install R" but on CentOS and RHEL you may first need to "yum install epel-release".
