The R Tools > Data Science Settings command affects also a number of different settings in Visual Studio overall. This command is described in the next section.
R Tools > Data Science Settings
The R Tools > Data Science Settings menu item configures the Visual Studio IDE with a layout that's optimized for the needs of data scientists. Specifically, this option opens the Interactive, Variable Explorer, and Workspaces windows:
To revert to other Visual Studio settings later on, first use the Tools > Import and Export Settings command, select Export selected environment settings, and specify a file name. To restore those settings, use the same command and select Import selected environment settings. You can also use the same commands if you change the data scientist layout and want to return to it later on, rather than using the Data Science Settings command directly.
Text Editor > R > Advanced options
These options control the behavior of formatting, IntelliSense, outlining, indenting, and syntax checking for R.
Each option is set to either on or off to control the behavior in question. For details on what each option affects, look at the help pane at the bottom of the dialog box. Note that you can drag the top of that help pane up to make the pane larger.
