[R] moving functions between namespaces

[Faber Fedor]

Hi all,

I'm a newbie wrt R but that's okay, since I don't do any programming
in R.  What I do need to do is to administrate the activites of an R
programmer, so my questions will be related to adminning R as opposed
to statistcal programming.  I hope that's okay with y'all. :-)

I've been through most of the docs that I could find (the PDFs,
StatsRUs, etc.) and I've found the answers to most of my questions,
but not to an important one: how do I move a function from one
namespace to another.

On the chance that I'm not using the right terminlogoy, here's my
situation: Programmer A has written a function foobar() which resides
in his namespace /home/progA/.RData.  I want to move foobar(), and
only foobar(), into the QA enviroment which means replicating foobar()
inside of /home/qa/.RData.

I've found that I can use sink() to copy foobar() to a file but 1) I
haven't found how to read it back in and 2) I figure you guys have a
more elegant way of doing this.

Any advice?
