If it's an informational message, like one you might log, use message().
If
you're rendering an object as text, like in a show method, use cat().
Another thing to consider is that messages can be suppressed with
suppressMessages() but cat() output cannot.
Sure. What I cannot decide is whether that is good or bad.
Returning to this part of the thread, and mostly just 'for the record', it turns
out that
http://bioconductor.org/developers/package-guidelines/#messages
says
End-User Messages
* `message()` communicates diagnostic messages (e.g., progress during lengthy
computations) during code evaluation.
* `warning()` communicates unusual situations handled by your code.
* `stop()` indicates an error condition.
* `cat()` or `print()` are used only when displaying an object to the user,
e.g., in a `show` method.

Should I use cat() or message() (or something else) for
if(verbose) cat("my message\n")
