Subject: local weight and coef from LOESS or locfit

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?
