I am not able to install packages in RStudio. Can anyone help me please? I`m using the newest version of RStudio.
This is what it says, when I try to install a package:

Warning in install.packages :
** unable to access index for repository https://cran.rstudio.com/src/contrib:**
** kann URL 'https://cran.rstudio.com/src/contrib/PACKAGES' nicht öffnen**
Warning in install.packages :
** package ‘car’ is not available (for R version 3.6.1)**

This is a connectivity issue, R is not been able to connect to the CRAN repository, is your internet connection behind a firewall or proxy server? this is usually the case when you are at work or school.

Another thing to try is to disable secure download
