[R] How do I make a Sweave + latex table out of this ?

[David Whiting]

Hi Fredrik,

You can do this nicely with latex() if you massage this a little so that
you end up with a data frame that includes a column for agemF (to
indicate which agemF each row belongs to) and then use the rgroup and
n.rgroup options of latex().
