Answers:

Yes, this is a problem. Rtools is a collection of tools necessary for building R packages in Windows. You need to have Rtools installed over your system to install packages. Kindly refer to the following link for installing Rtools - https://cran.r-project.org/bin/windows/Rtools/

The error message is indicating that either R or RStudio is not able to access the internet. Make sure that your internet connection is working correctly. Also, make sure if your system's firewall is preventing either R or RStudio from accessing the internet or not. Sometimes it even happens that the antivirus software also stops third-party tools like RStudio from accessing the internet. You can also google the error message and try to find a suitable solution.
