epifitter 1.0.0

CRAN release: 2026-04-12

Modernized the fitting workflow with shared input validation, more informative error messages, and improved grouped-model ergonomics.
Refreshed the documentation site with updated articles, improved accessibility, dark mode support, and a clearer visual style for figures.
Added a formal package citation, a vignette built around the bundled PowderyMildew dataset, and expanded regression tests for area summaries and model fitting.
Corrected area-under-the-curve handling for repeated assessment times and strengthened defaults for nonlinear fitting workflows.
Added optional confidence bands to plot_fit() with residual and wild bootstrap interval methods.
Strengthened simulation input validation and corrected the logistic simulation equation when K is lower than 1.
Added optional weighted nonlinear least squares to fit_nlin() and fit_nlin2(), including custom numeric weights, custom weight functions, and fitted-value weighting methods ("binomial", "mean", "cv", and "power") for proportional disease intensity data.

CRAN release: 2021-06-14

Including dataset PowderyMildew containing experimental data of disease progress curves of powdery mildew under different irrigation systems and soil moisture levels in organic tomato
Included the option to define the maximum asymptote K when simulating disease progress curves using the function sim_monomolecular(),sim_logistic(), and sim_gompertz()

CRAN release: 2020-11-25

Added a warning to the functions fit_nlin() and fit_nlin2() for when the user insert disease intensity data out of the interval 0 and 1.
Added a NEWS.md file to track changes to the package.

fixed a problem with the fit_lin() $data output.
