[R] contrasts with aov

Hi all,

I'd like to carry out what amounts to a succession of paired t-tests
across units in a repeated measures design.  I thought I could
accomplish this using aov with an Error argument and the contr.sdif
functon from the MASS package. But the "summary" function does not return
the results of the contrast analysis (as it does with lm).  Is there any
way to get the kind of table lm produces with a call to summary (e.g.
Estimate Error t value Pr(t>|t|))?
