title: RStudio syntax formatting - Bold function names
body: <p>I'm reading through Hadley Wickham's <a href="http://adv-r.had.co.nz/" rel="nofollow noreferrer">Advanced-R</a> web text and noticed that the code is shown has syntax highlighting that bolds the names of functions. I find this incredibly easy to read and I was wondering how I might be able to apply that to my own code?</p>
