I am troubled by the curly brace "rule":

An opening curly brace should never go on its own line and should always be followed by a new line; a closing curly brace should always go on its own line.

It seems to me that the opening an dosing curly brace should go on their own lines to allow the reader to immediately know what is encompassed in the curly brace:

Rather than:

if (y < 0 && debug) {
  message("Y is negative")

How about (note use of separate line for braces and use of indentation):

if (y < 0 && debug) 
     message("Y is negative")

Am I missing something regarding the R parser or syntax?

I made my own version that reflects my personal biases:
