Message saying "would you like to use a private library instead?" when trying to install a package

Question

I'm trying to install a package in R called epiR and the console opens this dialog for me.

install.packages('epiR')

what do i do ?

Answer 1

Your system does not contain a personal library where all the packages will be saved. When a dialog appears asking if you’d like to use a personal library instead, click on yes.

Answer 2

This question appears if your user environment is restricted such as on a cooperate network. Opening [R] with administrative privileges will resolve the issue. 

So say no. 

On windows open [R] by right clicking and selecting "Run as Administrator"
