Note that on Windows, you will need Rtools installed for devtools to work. Rtools is not a R package, but a set of tools for building/compiling R packages. You can download it from: https://cran.r-project.org/bin/windows/Rtools/

Once installed, start R, load devtools, and run find_rtools() to check that Rtools has been successfully installed and detected. You should get:

library(devtools)
find_rtools()
