This tutorial explains multiple methods to update R.
Method 1: Update R Automatically
R can be easily updated with "installr" package. To update R on MacOS, you need to use "updateR" package instead of "installr" package.
Windows: installr
install.packages("installr")
library(installr)
updateR()
Mac: updateR
install.packages("devtools")
devtools::install_github("AndreaCirilloAC/updateR")
updateR(admin_password = "PASSWORD") # Where "PASSWORD" stands for your system password
The dialog box will be opened to take you through the following steps -
- It checks for a newer version of R.
- If one exists, the function will download the most updated R version and run its installer.
- Once done, the function will offer to copy (or move) all of the packages from the old R library to the new R library.
- It will then offer to update the moved packages, offer to open the new Rgui, and lastly, it will quit the old R.
Method 2: Install and Update R Manually
- Go to the CRAN website.
For Windows Users - https://cran.r-project.org/bin/windows/base/.
For Mac Users - https://cran.r-project.org/bin/macosx/ - Download the latest R installer.
- Run the installer, and it will guide you through the installation process.
- After updating R, open RStudio. Close RStudio if it is already opened and open it again.
