Peter,

How about something like this:

> x
            deg0NA deg4NA deg8NA deg0NP deg4NP deg8NP
(Intercept)    462    510    528    492    660    762
IV1              1      2      3      4      5      6


> x[1]
(Intercept)
        462

> str(x[1])
 Named num 462
 - attr(*, "names")= chr "(Intercept)"


Does that work or am I missing something?
