Warning message when installing devtools

Question

When I try to install devtools in Rstudio 3.2.3 (Windows 10) using the command install.packages("devtools"), I get the following message:

warning in install.packages :

'lib = "c:/Program Files/R/R-3.2.3//library"' is not writable

I'm a newby and I've been hunting for solutions but so far am coming up empty. I would appreciate any advice that might get me through this step. Thanks.

Answer 1

I stumbled upon the same issue earlier. This "problem" arises when you try to install a library for the first time and R does not have a a dedicated library for it yet.

Two pop-up should appear one after the other when you try to install a package like:

install.packages("ggplot2")

The questions are the following:

• Would you like to use a personal library instead?
• Would you like to create a personal library 'C:\Users\bartlein\Documents/R/win-library/3.2' to install packages into?

Answer yes to both questions and you should be fine.

The ressources I used came from here.
