local weight and coef from LOESS or locfit

Hi, there,

Could someone tell me is there any way to get the local weight , local 
parameters estimation for each  points when using LOESS or locfit packages?

Thank you very much!

AFAIK they are not available, both in principle (the packages fit at a 
smaller set of points and interpolate) and in practice (the fits at the
points where fitting is used are not retained in the Fortran/C code).

So it looks like the designers saw no need for these to be available, and 
neither do I.  Given that loess and locfit are rather different (and
KernSmooth has locpoly too), *why* do you want these components of the 
fits?
