There are packages for this now!

2017-08-03: Since I wrote this in 2014, the universe, specifically Kirill Müller (https://github.com/krlmlr), has provided better solutions to this problem. I now recommend that you use one of these two packages:

• rprojroot: This is the main package with functions to help you express paths in a way that will "just work" when developing interactively in an RStudio Project and when you render your file.
• here: A lightweight wrapper around rprojroot that anticipates the most likely scenario: you want to write paths relative to the top-level directory, defined as an RStudio project or Git repo. TRY THIS FIRST.

I love these packages so much I wrote an ode to here.

I use these packages now instead of what I describe below. I'll leave this gist up for historical interest. 😆

                var sel = editor.getSelection("\n");
                // Indent only if there are multiple lines selected, or if the selection spans a full line
                if (sel.length > 0 && (sel.indexOf("\n") > -1 || sel.length === cm.getLine(cm.getCursor().line).length)) {
                    cm.indentSelection("add");
                    return;
                }
            }
