Hypothesis: datasets in a ..library/data/Rdata.rds file whose listing does
not match the name of the dataset from which it is derived will cause the
behavior in question.
And Terry; After executing `data(package-"survival")` I must mention that the
spelling of "Granulomatous" is not "Granulotomous", and neither is the spelling
of "gammapathy", "gammapothy".
