logical; if TRUE a matplot() of all the
coefficients in the list against the relative bound (absolute bound if
relative is not present) is plotted. Otherwise no plot is done.
all
logical; if FALSE, then only the non-zero
coefficients are returned.
constrained
if TRUE then only the coefficients that were constrained
are returned.
type, xlab, ylab, …
further arguments with useful defaults
passed to matplot.
Value
A matrix with the bound(s) (relative [if used] and absolute),
the Lagrangian(s) and coefficints of the fitted model(s).
