S4 can be considered a "new code" and given that R is becoming more and more
S4-rish that is probably the way to go.
As far as I can see S4 is written in camelCase almost exclusively:
- functions start with small letters and try to give as complete description by
means of an action verb (i.e. setRefClass, getMethod)
- non exported functions start with "."
- variables are also camelCased but tend to be shorter and start with
a noun (i.e. elNames, envRefClass)
