I think so (a little hard to reconstruct).

I can't parse the last sentence.  I'm guessing you mean enable
ess-developer and then load the appropriate source file or function.

Now I'm in a mess: I set a breakpoint on one function in a package.
That worked the first time.  Then I flagged a function it called (also
in the package) for debugging.  Now I don't stop at the breakpoint and I
don't get the usual break for debug(fn).  I also tried debug(fn) on the
R command line.  Still no dice.  Both functions are exported by the
namespace.

I don't see any inappropriate functions in the global namespace, and the
log showed 
devSourcing 'rclusbin3.R' ...
missreg2 at PKG:   FUN[rclusbin3]
missreg2 at NS:    FUN[rclusbin3]
when I C-c C-l the file for the outer function; that's the right
namespace.

I'm trying to fix it or get it into a manageable example.

It might be relevant that the outer function being debugged is
relatively slow, ~ 6 minutes.
