This means “Load the contents of the file into my console’s runtime every time I save the file”. Apart from some self-explanatory buttons, and others that needn’t concern you at this starting point, there’s also a “Source on Save” checkbox. This is, for all intents and purposes, identical to every other code editor’s main window. It’s where you write R code you want to keep for later - functions, classes, packages, etc. I’ll explain the default order, though note that this can be changed in Settings/Preferences > Pane Layout. You could write R code in simple text files as in most other languages, but that’s really not recommended given how many commands there are and how complex things can quickly get.Īfter you’ve installed the tools, launch R Studio.
R will be installed as the underlying engine that powers RStudio’s computations, while RStudio will provide sample data, command autocompletion, help files, and an effective interface for getting things done quickly. download and install RStudio, the R IDE: Both are free, both open source.
There are two steps to getting it installed:
R is both a programming language and a software environment, which means it’s fully self-contained.
