objects that are supplied as arguments are averaged in a way that makes sense for the object class, i.e. taking into account the particular bad-data codes of that particular class.
# S4 method for amsr composite(object, ...)
An amsr object.
Other amsr objects.
Form averages for each item in the
data slot of the supplied objects,
taking into account the bad-data codes. If none of the objects has good
data at any particular pixel (i.e. particular latitude and longitude),
the resultant will have the bad-data code of the last item in the argument
The metadata in the result are taken directly from the metadata of the
final argument, except that the filename is set to a comma-separated list
of the component filenames.
