I have to use a specific program in R 3.1.3
For that purpose whenever I am trying to install any package it is throwing error
unable to access index for repository http://cran.r-project.org/bin/windows/contrib/3.1
Apparently, it seems the directories in the repos are available from version 3.2 onwards. Here, I am trying to install shiny package.
Hw to resolve this problem?
