Hello everyone, today I updated the version of R, since then I have had problems with the installation of packages. Every time I need to work with one and try to install it, the following alert appears:
"One or more of the packages thet will be uplated by this installation are currently loaded. Restarting R prior to updating these packages is strongly recomended.
Rstudio can restart R and then automatically continue the installation after restarting (all work and data will be preserved during the restart.
Do you want to restart R prior to installing?"
I tried clicking "Yes" but nothing happens, and the package doesn't install most of the time, and when it does, this message appears:
Even when I want to work with the functions of the package I already installed, I have to install it again, as it results in error, like "nonexistent options".
Please give me advice how to fix the problem!
