R Tools is missing. https://cran.r-project.org/bin/windows/Rtools/

This seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.

• Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.
  
  
• Disable secure download setting.
  
  
• Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.

choosing a different CRAN repository and disabling secure download did the trick... thank you very much
