I pride myself on having an extensive and comprehensive test suite for

However, I don't have a good procedure for testing the plotting
routines. (Forget "good", I don't even have a third-rate procedure for
this.) This was brought home with the latest release; within 24 hours I
got a note about a problem. They y-axis range for a plot was calculated
incorrectly, giving no warning or error, just a graph with 2/3 of the
data outside the plot window. It was a side effect of a change for
another reason, and of course I had checked out that consequence
thoroughly.
Any good ideas for this issue?

The R tests are comparisons of uncompressed PDF files (which are almost
text files). See the 'tests' directory.
Paul Murrell gave a talk about another method at an early DSC:

graphicsQC package.
