[solved] Can't install any R package on Jupyter Lab notebook

 Interestingly I could install R packages from terminal sudo R

It turned out that the folder that Jupyter Lab R points to is different from what sudo R points to as well.

Eventually, to solve the problem, Martin wiped out my R installation directory. And probably it's a good idea for me not to install packages on sudo R but from notebook directly then.

 You may click on the play button of a song in an album but nothing happens.
