Make sure that you have installed the latest versions of R and RStudio.
In RStudio, install the devtools and educer packages. This will install all of the tidyverse packages and other resources.
Install the lmerTest and roxygen2 packages by entering the following code into the console:
if (!require(lmerTest)) install.packages("lmerTest")
if (!require(roxygen2)) install.packages("roxygen2")
