I would like to install tidyr onto my computer. However I am not able to from US CRAN. I tried changing to different sites, for example Canada and in each instance I receive an error of the type:
So, I go to the website and look for the zip file and in all instance: US, Canada, Mexico etcetera the folder is not there. I am at a loss here. What am I doing wrong ?
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.
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.
