I had trouble with some tests for the survival suite last night that I
cannot explain.
Framework: Ubuntu Linux, R2.11.
For testing survival I have a separate directory and Makefile. I
pull everything into the local .RData, no packages, library, or
namespace. (It's easier to add test modifications to a routine in a
chain of calls).
A test of survreg + psline would fail because splines is not
automatically loaded in this scenario. In my console window type
> library(splines)
> fit <- survreg(Surv(time, status) ~ ph.ecog + spline(age),
data=lung)
as the first 2 lines a a new session (the lung data is also saved)
and up would pop an error message about having <2.10 version of
survival. And it is true that I had such a thing in my ~/RLib. But
there is no mention of either the local or the system survival library
when I type search(), and .Autoloaded is NULL.
Could you show us the result of .libPaths(), search(), searchpaths() and
sessionInfo()?

I'm mystified as to how R decided to use that library, and what it was
trying to pull from it. I removed it from ~/Rlib and the message went
away, but now I'm not so sure that this was a good idea. Is something
now being automatically snatched out of the standard survival library?
If so that compromises the integrity of my testbed. How do I find out?
