ec50estimator: An Automated Way to Estimate EC50 for Stratified Datasets

Estimates effective concentrations that reduce growth by 50 percent (EC50) in multi-isolate and stratified dose-response experiments. The package wraps model fitting from drc, returns data-frame outputs, and provides helper functions for data checks, model selection, fitted-curve plotting, prediction, diagnostics, and reporting. Information about drc is available in Ritz C, Baty F, Streibig JC, Gerhard D (2015) <doi:10.1371/journal.pone.0146021>.
