Custom conda package not available in R after installing from conda

Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers. Not required for this type of question, though.

I don't have enough experience using conda as a package manager to offer suggestions to fix this , so all I can essay is that it is best reserved for the job it was designed for, superbly, as a Python package manager.
