Updating R Kernel for JupyterLab in Anaconda

Hi,

I just installed Anaconda. Within JupyterLab, I installed the R Kernel and works well, except for the version of R is quite old and most of the libraries I need cannot be installed in versions before 4.

I’ve tried couple of things without success, such as the explanation given here:

Any ideas on what I can do?

Thanks
