To give yourself a head start, check out some basic R commands every beginner should know.

When you are not sure where your script is at, try clearing everything and then selecting the entire script and running it.R is a well-supported language with a huge library of built-in functions you can use to analyze data. Now you can start writing much larger scripts that execute a series of operations. Plots: From the 'Plots' menu, select 'Clear All.'.Workspace: From the 'Workspace' menu, select 'Clear All.'.

Console: From the 'Edit' menu, select 'Clear Console'.

This workspace will be reopened each time you open RStudio. However, the other panels are a little different and are saved together in a workspace when you exit RStudio. The scripts in RStudio work very much like individual files in editors and spreadsheet packages.

Try entering several lines of code now and clicking run. The Run button will execute one line of code if you have the blinking caret, otherwise, it will execute a selected block of code. You should see the results of running the script appear in the console panel. Try typing a command into this panel and then press the 'Run' button shown below. In RStudio, select 'New Script' from the 'File' menu. While the tutorials will get you started using R in an 'interactive' mode, you'll want to start writing larger scripts. The sections are by topic and the More on RStudio Introduction to R - very concise introductionįrom here, go through each of the topics in the contents for this web site. I would recommend reviewing it periodically. While this tutorial contains a great deal of documentation on R, it moves rather quickly and also introduces concepts that are not key to spatial statistics. A link to it is provided below and I recommend going through the tutorial in detail before proceeding.īelow is a link to the introduction to R that is on the R web site. The tutorial will talk you through the basic operations of R and explain how R works with data, operations, and functions. The best introduction to using R is a 'self-learn tutorial from The National Center for Ecological Analysis and Synthesis at The University of California at Santa Barbara. Now, you can continue on with the tutorial below by just using the 'R Console' on the left-hand side of RStudio.

Press escape ('esc') and hit return to get back to the '>' prompt.

If a plus sign ('+') appears while in the console, it means that R is wanting you to enter some additional information. This is where you'll type R Commands to immediately execute one command at a time.

There are only a few things you need to know about using R Studio to get through your first tutorials.Ĭlick in the 'Console' and you should see a blinking 'caret' appear next to the greater than sign ('>'), referred to as a 'prompt'. On the bottom right is a pane that will display plots you create. On the right is a 'Workspace' panel that will show you the variables (also known as 'objects') that you are working with in R. In the left-hand pane is a 'console' window for R command. Across the top is a standard menu bar with typically menu items that we will look at in a little while. Open RStudio and a window like the one below should open.
