I'm getting ready to submit an update of survival, and is my habit I run the
checks on all
packages that depend/import/suggest survival. I am getting some very odd
behaviour wrt
non-reproducability. It came to a head when some things failed on one machine
and worked
on another. I found that the difference was that the failure was using the
3/27 release
and the success was still on a late Jan release. When I updated R on the
latter machine
it now fails too.
An example is the test cases in genfrail.Rd, in the frailtySurv package. (The
package
depends on survival, but I'm fairly sure that this function does not.) It's a
fairly
simple function to generate test data sets, with a half dozen calls in the test
file. If
you cut and paste the whole batch into an R session, the last one of them
fails. But if
you run that call by itself it works. This yes/no behavior is reproducable.
Another puzzler was the ranger package. In the tests/testthat directory,
source('test_maxstat') fails if it is preceeded by source('test_jackknife'),
but not
otherwise. Again, I don't think the survival package is implicated in either
of these tests.
Another package that succeeded under the older r-devel and now fails is
arsenal, but I
haven't looked deeply at that.
Any insight would be be appreciated.
