Well, I'm pretty sure that, inside package A, calling B::functionName
will not work if B has not been imported. That's why I use ::: (after
spending some time trying to figure out why :: didn't work). At least
that was the state of affairs as of R 2.9 or so, perhaps things have
changed since then.

will probably just stick with it.

Dear all

Dear all,
I am generating a number of lattice plots with common axes but varying
legends. There is one plot in the window at a time. I would like the
plot axes to always appear in the same place within the window (and
saved images) so the plots do not move around when they are combined in
