Analysis and Simulation of Plant Disease Progress Curves R package epifitter version 1.0.0 CRAN Task View: Agriculture (https://CRAN.R-project.org/view=Agriculture) CRAN Task View: Epidemiology (https://CRAN.R-project.org/view=Epidemiology) Tools for analysis, visualization, and simulation of plant disease progress curves. Includes functions to calculate area-under-the-curve summaries, fit and compare exponential, monomolecular, logistic, and Gompertz models using linear or nonlinear regression, work with single or multiple epidemics, and produce 'ggplot2'-based visualizations. Also includes an experimental powdery mildew dataset for reproducible teaching and research workflows. See Madden, Hughes, and van den Bosch (2007) <doi:10.1094/9780890545058> for background on the epidemiological methods.
