I pride myself on having an extensive and comprehensive test suite for the survival package.
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?
