Regarding installing packages
Whenever I type the install.packages command, I get the first line in red color as
"WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:"
Is this a problem??

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/
