Then perhaps a before and after section might be
helpful. Example of awful coding and the 'preferred'
approach, hopefully commented as to why it is better?
A real problem that I have encountered with ?help is
that the help is very good if you know a lot about R
in the first place. If, like me, you're just learning
the basics often the help examples are terse enough or
include enough other odds and sods that it can take a
long time to figure out what is and what is not
essential to get a procedure to work.
