Menu and click “Check for R Updates” (see image below). If you do that, R will tell you the current version you’re on, and whether or not there is a more updated version that you can download (circled in blue).Alternatively, if you’re in RStudio, you can type and run “sessionInfo()” in the R Console. The first line that the console returns is the version of R that you’re using. You can then download and install the latest version of R here for Mac, and here for Windows.If you’re using a Windows computer, you may need to uninstall R to update it. You can find a quick guide for that here. Another great option for Windows users is to use a package called installr (unfortunately only available for Windows, @Mac users). All you need to do is install “installr”, load up the library, and run the code “updateR()”. This function will check for newer versions and will guide you through the update process.If you want to update to the latest version of RStudio, hover over “Help” on the top menu bar of your Mac, and click “Check for Updates”. Then, quit the RStudio program, go to the RStudio website, and download and install the latest version.Now you should have the latest versions of R and RStudio on your computer. I hope this tutorial was helpful!As a quick note: my “Basics of R” course uses R version 4.0.2 and RStudio version 1.3.959. There shouldn’t be any incompatibility issues if you’re running a slightly different version, but it is usually best to stay up to date with your software!If you liked this post and want to learn more, then check out my online course on the complete basics of R for ecology:Start learning nowAlso be sure to check out R-bloggers for other great tutorials on learning R
