Error saying Error in install packages epiR unable to install packages when trying to install a package

Question

I'm a noob in R and i'm trying to install a package. I used the function install.packages(). The console threw a message asking would you like to use a personal library instead and clicked on no and following error popped up. Why is this happening? Do I need to use a personal library?

Error in install.packages("epiR") : unable to install packages

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.
