Support for Function gam()

DESCRIPTION:

The character vector gam.slist has by default the values c("s", "lo","random") . This supplies gam() with a set of smoothers that are available, that have been properly interfaced with the gam() fitting algorithms. Thus since "s" is in this list, then all terms of the form s(age) in a formula will be designated as "special" by the function terms(), and indicate that a smoother is available for smoothing against its argument. An entry in this vector, say "s", implies the presence of a function glm.s().
The vector gam.wlist is currently initialized to c("s","lo"), and indicates what special, efficient backfitting algorithms are available when all the terms in the additive model are to be fit with the same type of smoother. An entry, say "s", in this table indicates the presence of a function s.wam().
