[R] aggregating data with Zoo

Is there a way of aggregating 'zoo' daily data according to day of week?
eg
all Thursdays

I came across the 'nextfri' function in the documentation but am unsure
how
to change this so any day of week can be aggregated.

I have used POSIX to arrange the data (not as 'zoo' series) according to
day
of week, but am curious if I've missed if a similar option available with
zoo.

Thank you for any help,
