RStudio also makes it easy to start new or find existing projects. It also enhances productivity and supports authoring HTML, PDF, Word Documents, and slideshows too. RStudio includes powerful coding tools designed to develop and publish such packages. One of the main advantages of R is that, If the function you want isn’t available you can write your own package and share it with the world.

You can either type the name of a function in the search window or use the code to search for a function with the name. Packages can also be installed using the command (in console), like this one below: install.packages("tidyverse") Packages that are loaded in the current session are checked while those that are installed but not yet loaded are unchecked. Shows a list of all the R packages installed on your hard drive and indicates whether or not they are currently loaded.

There are buttons for opening the plot in a separate window and exporting the plot as a pdf or jpeg (though you can also do this with code using the pdf() or jpeg() functions.) One nice feature of the “Files” panel is that you can use it to set your working directory – once you navigate to a folder you want to read and save files to, click “More” and then “Set As Working Directory.” We’ll talk about working directories in more detail soon. The files panel gives you access to the file directory on your hard drive.

The history window shows all commands that were executed in the console. you can also declutter the panes in the screen, or just minimize the window by clicking the minimize button on the top right of the panel. As you get more comfortable with R, you might find the Environment / History panel useful. You can also see information like the number of observations and rows in data objects. The Environment tab of this panel shows you the names of all the data objects (like vectors, matrices, and dataframes) that you have defined in your current R session. You can type code directly into the console after the prompt and get an immediate response, just like any REPL.įor example, if you type 3+5 into the console and press enter, you will see that R immediately gives an output of 8. This is a prompt that tells you that R is ready for new code. At the beginning of the console you will see the character. By default, It is present at the bottom left of the window. That way, if something on your computer crashes while you are working, RStudio will have your code waiting for you when you re-open RStudio, as it has recovered the code that you were editing. Before you start typing in an untitled R script, you should always save the file under a new file name. When you open RStudio, it will automatically start a new Untitled script. R scripts are just text files with the “.R” extension. The source pane is where you create and edit R Scripts” – your collections of code. Let’s see about each window briefly: Source When you launch RStudio, you will see the following four windows or panes. It includes a console, syntax-highlighting editor that supports direct code execution, as well as tools for plotting, history, debugging and workspace management.
