[R] How to Update R

This post covers how to update R.

There are a few options to update R, but I believe this is the most convenient way.

Note that it is better to run the source code below in R Gui, but it is still possible to do it in RStudio.

install.packages('installr')
library(installr)
updateR()

To update R Studio, you can follow these steps:

1. Open R Studio on your computer.

2. Go to the "Help" menu located at the top of the R Studio window.

3. In the "Help" menu, click on "Check for Updates" option. This will open the R Studio Updates dialog box.

4. The dialog box will display the current version of R Studio installed on your computer and the latest available version.

5. If there is a newer version available, click on the "Download" button to download the latest installer package for R Studio.

6. Once the download is complete, locate the downloaded installer package on your computer and double-click on it to run the installer.

7. Follow the instructions provided by the installer to update R Studio. This typically involves accepting the license agreement, selecting the installation location, and confirming the update.

8. After the update process is complete, you can launch the updated version of R Studio and verify the new version number by going to the "Help" menu and selecting "About R Studio".
