R devel - Jun 2018 - new behavior in model.response -- Solved

Thanks to multiple readers for comments and patience as I sorted this out.? I
now have
working length and names methods for Surv objects, which do not seem to break
anything.??
I just ran the test suites for 471 packages that depend on survival, but I
don't test
against bioconductor so cannot speak to that corpus.

Essentially, if I wanted to think of? Surv(1:6, rep(1:0, 3)) = 1 2+ 3? 4+ 5? 6+
as a
vector of length 6, although stored in a longer representation, I needed to
 ? a. add a length method
 ? b. add names and names<- methods
 ? c. But, the names method cannot create a length=6 names attribute.? Handling
of a names
attribute is baked into the low-level code, and that code treats number of
elements as the
length, no matter what you say.
 ? d. The solution was to make names.Surv store the results in the rownames.
