accept_port_fit: Accept or reject a non-converged port fit

In mnirs: Muscle Near-Infrared Spectroscopy Processing and Analysis

Accept or reject a non-converged port fit

Description

stats::nls() with algorithm = "port" and warnOnly = TRUE returns a model whose stop certificate failed. It is kept with a warning when ok holds and its coefficients are finite; otherwise it is reported as an error and dropped. The port stop code is reported in prose either way.

Usage

accept_port_fit(model, on_error, ok = TRUE)

Arguments

model	An nls model or NULL.
on_error	A reporting function; see fit_td_fallback().
ok	Logical; a further acceptance condition, e.g. an RSS no worse than the starting estimates. Evaluated only for a non-converged fit.

Value

model or NULL.
