2.2 Introducing RStudio

20210103 The RStudio interface includes an R Console on the left through which we directly communicate with the R software. The window pane on the top right provides access to the Environment within which R is operating. This includes data and datasets that are defined as we interact with R. Initially it is empty. A History of all the commands we have asked R to run is available on another tab within the top right pane.

The bottom right pane provides direct access to an extensive collection of Help. Another tab within this same pane provides access to our local Files. Other tabs provide access to Plots, Packages, and a Viewer to view documents that we might generate.

In the Help tab displayed in the bottom right pane of (intro:fig:rstudio_startup), for example, we can see links to the R documentation. The manual titled An Introduction to R within the Help tab is a good place to start if you are unfamiliar with R. There are also links to learning more about RStudio—these are recommended if you are new to RStudio.
