Thanks for that Stephen. It works nicely. It seems that my expectations for the plot defaults were non-standard. From your remarks and those of a colleague with an engineering background, I guess the defaults are standard. As a biologist, it seemed sensible to me to expect it to work like a compass though. Future updates to the plotrix package apparently might include options to easily customize these features (thanks to the package maintainer).
