Extract Model Coefficients of a vgam() Object
Extracts the estimated coefficients from vgam() objects.
coefvgam(object, type = c("linear", "nonlinear"), ...)For VGAMs, because modified backfitting is performed,
each fitted function is decomposed into a linear and nonlinear
(smooth) part.
The argument type is used to return which one is wanted.
A vector if type = "linear".
A list if type = "nonlinear", and each component of
this list corresponds to an s term;
the component contains an S4 object with slot names such as
"Bcoefficients",
"knots",
"xmin",
"xmax".
