I'm working on a document that is a cross of user's guide and a technical manual. I describe a system which has variables that I handle normally, then introduce an R package that I've written which deals with some of the same variable. My question is how to deal with the computer package-related components. For (1) the name of the package, (2) function (method) names, and (3) variable/parameter/argument names: Should they be set in a
\verb style inline and in equations? Should they be capitalized at the beginning of a sentence? Or should I avoid using them at the beginnings of sentences?
Essentially, I'm asking a broader version of How to typeset variables and other code?.
