loess() is a 'local' fitting procedure, which means that it fits a 
different regression at each prediction point. (In principle, for there 
are computational short cuts: see ?loess.control.)  Since each fit is only 
used for a single prediction, its coeffiicients are not of interest and 
not made available.
