RStudio syntax formatting - Bold function names

Question

I'm reading through Hadley Wickham's Advanced-R 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?

Answer 2

In the latest version of RStudio (I'm working with v1.1.4), you can enable an option to highlight functions calls.

Simply check the box in Tools > Global options > Code > Display > "Highlight R functions calls".
