Re: [jupyter] Re: Jupyterlab defaulst to Python3 Kernel

Kevin, Again thanks a million. It's nice to keep hearing encouraging and helpful replies. I successfully installed everything and all works as it should. For anyone who might run in to such an issue, where either R or Julia and i suspect any other kernel, to make sure you have the latest versio

Re: [jupyter] Re: Jupyterlab defaulst to Python3 Kernel

Re: [jupyter] Re: Jupyterlab defaulst to Python3 Kernel

Kevin, Thank you so much for your help. The name issue makes sense now. The issue with the R kernel is that it doesn’t generate any errors. It just simply will not run the code and suddenly, instead of the active kernel is R, changes to no kernel. Julia, on the other hand, generates messages
