B Introduction to
RStudio is the premier integrated development environment (IDE) for
R. It is available in open source and commercial editions on the desktop (Windows, Mac, and Linux) and from a web browser to a Linux server running RStudio Server or RStudio Server Pro.
You can find a global view of the IDE in this Cheat Sheet.
An important advice is that for running a line or code selection from the script in the console, you can do it with the keyboard shortcut
'Ctrl+Enter' (Linux) or
'Cmd+Enter' (Mac OS X).
