I have a debugging environment for the survival package, perhaps unique to me,

it works very well.
To wit, a separate directory with copies of the source code but none of the

contain a copy of
src/init.c
Within this I use R --vanilla, attach my .RData file, survival.so file, and
away we go.
That is, until my first useage of it today under R 3.0. My runs get into
trouble with
messages about
"conflicts with the survival namespace". My problem is that I can't figure out
where or
how the name space is being searched out and attached. Any hints on where to
look would be
appreciated. This "magical" load is
kind of spooky.
Here is a session that displays it. The "setup.s" file does the dyn.load and
attaches some
data sets.
I don't know a direct way to find this, but you could add some debugging code to
the .Onload function in survival, e.g. to print what the stack is like when it's
loading. That should be informative.
trace(loadNamespace, quote(if (package == "survival") recover()))
will break into ?recover when survival is being loaded.
