sigma.breathtestnlmefit

Functions for <code>nls</code> and <code>nlme</code> are available; 
additional functions for Stan-based fits are defined in package <code>breathteststan</code>.

Reads several formats of 13C data (IRIS/Wagner,
BreathID) and CSV.  Creates artificial sample data for testing.  Fits
Maes/Ghoos, Bluck-Coward self-correcting formula using 'nls', 'nlme'.
Methods to fit breath test curves with Bayesian Stan methods are
refactored to package 'breathteststan'. For a Shiny GUI, see package
'dmenne/breathtestshiny' on github.
