Thanks to Dirk and Duncan
Dirk's suggestion of the suppressMessages function unfortunately doesn't
quite do the job. The warning message isn't printed, but it is picked up
by the check function and leads to a whinge.
Duncan is right - I had an older version of "maps" and installing the
new version fixed the problem that was causing the warning in the first
place. (My apologies for not including sessionInfo).
So, the outcome is:
1) If you try to use require or library in help page examples,
everything has to work.
2) If you use require or library, wrap it in
suppressPackageStartupMessages so that the "Loading package" message
doesn't mess up your elegant code.
3) Remember that 2) won't stop any errors or warnings from being
recorded during package checking, therefore 1).
Is my logic sufficiently circular?
