There are two good reasons. Explore the other options in the Editor pane….we’ll be using them later on but take a sneak peak for now.If it opens with another program, right click on the file and see if you can set the “open with” default to RStudio. Navigate to your file, chapter2.R and double click on it.If by chance you are prompted as to whether to save the workspace image, select “Don’t Save” (otherwise all of the objects in your Global Environment will be saved for later use – there’s no need for this now). Save the script file that you have just created to your new directory, and name it “chapter2.R”.The specific location is not relevant as long as you know where it is.

You should notice that your curser dropped down to the next line. To send code to R, place your curser anywhere on the line to be executed, then press the Run button in the upper right hand portion of your screen. (These color schemes don’t appear in this ebook). Notice that this font is green (by default) in RStudio this helps you quickly differentiate between comments and code. Make sure to paste in the comments too!Ĭomments are not actually executed in R – they are notes that you (the coder!) type to remind yourself of what the code is intended to do.
