Updating R

Windows

To update R on Windows, try using the package installr (only for Windows)

Open R and install and load installr.

> install.packages("installr")
> library(installr)

In R, execute the updateR() function. This will start the updating process of your R installation by: “finding the latest R version, downloading it, running the installer, deleting the installation file, copy and updating old packages to the new R installation.”

macOS

On Mac, you can simply download and install the newest version of R from https://cloud.r-project.org/bin/macosx/. When you restart RStudio, it will use the updated version of R.

Updating RStudio

From within RStudio, go to Help > Check for Updates to install newer version of RStudio.
