So, with the item in the original query:

if (x<-3) do_something;

if they wrote it as

if (x<(-3)) do_something;

there would be no problem (and no doubt about what went with what). Of course in complicated expressions this could induce an episode of ocular lispopia, but apart from that it's safe!

I've been reading Data Analysis Using Regression and Multilevel/Hierarchical Models by Gelman and Hill. I'm getting acquainted with my new cartoon character friends Elmer (lmer) and Bugs, and at some point it may become clear what is going on.

Michael Dewey: When I started I found the free documents useful but I made most progress when I bought MASS. I do realise that liking books is a bit last millennium.
Thomas Lumley: Very late last millenium, though. "When I were young[er] we didn't have all these fancy yellow books."
