Hadley et al.,
I was using the cast function to reshape some data (aggregate a melted
data frame) and I did not put in the fill and for the most part the
values that came out were fine, but there were value great than an
order of magnitude from the actual value. When I put in the fill
argument everything is okay. I don't provide a reproducible example
because the data set is to large to post to the list, but if you would
like to see it then I can provide it.
#this works
cast(x, Date+RiverMile+location~Order, sum, fill=0)
#this doesn't
cast(x, Date+RiverMile+location~Order, sum)

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
