I am trying to instal R in jupyter notebook after I updated recently my R version (currently it is 4.1.3). I passed line by line after the instructions but in the last step (did it in anaconda prompt), I faced this error message: Error in IRkernel::installspec() : jupyter-client has to be installed but "jupyter kernelspec --version" exited with code 1. I found similar errors in the net, but not with "exited with code 1." I think the update of the R-version has changed something in Anaconda and it is doesn't recognize by it (maybe re-install R in anaconda, but I am not sure if so, and how to do it). can someone help with it? thanks
