tidy.breathtestfit {breathtestcore}

Broom-style tidying methods for breathtestfit

Description

Broom-method tidy to streamline the results of class breathttestfit as generated by nls_fit or nlme_fit. Returns the fit coefficients and half-emptying time t50 with the Maes/Ghoos method; additional parameters should be extracted with coef.

Usage
