Run the installr or updateR command. Run the following command in RStudio to begin the update: Windows: install.packages("installr") library(installr) updateR() Mac (where PASSWORD is your system password): install.packages("devtools") devtools::install_github("AndreaCirilloAC/updateR") updateR(admin_password = "PASSWORD")

Allow the command to install the latest version of R. The "installr" or "updateR" package will check for a new version of R, download it, and install it for you.
