I can't understand how the plyr package is turning up here:

attached base packages:
[1] grDevices utils stats graphics methods base
other attached packages:
[1] lattice_0.17-26
loaded via a namespace (and not attached):
[1] grid_2.10.1 plyr_0.1.9
I can understand that lattice would be using grid without having that
package loaded, but I can't understand how plyr got there.
One way for this to happen is if you have a copy of a function from plyr
in your global environment. The functions in plyr reference its
namespace, so you'd get it loaded that way.
It wouldn't matter if that namespace hadn't become associated somehow
with a function I have somewhere else on the search path (thereby
rendering the function unfindable).
This doesn't make sense. If the function is on the search path, it
doesn't matter what namespace is associated with it: you'll find it.
If you have a function with the same name in globalenv() then you'll
have problems. The simple solution is to remove it (e.g. rm(f)); a
better long term solution is to *never* store anything in your workspace
between sessions. Start with a clean global environment each time.

My guess is that if I knew how that
happened, I'd then know why plyr is loaded by namespace. However, I'm
lost for ideas on how that could have happened.
Suggestions as to where I should be looking greatly appreciated. Or, even
if that's unknowable, how to remove the association between the namespace
and the function.
TIA
