specr: Conducting and Visualizing Specification Curve Analyses

Provides utilities for conducting specification curve analyses (Simonsohn, Simmons & Nelson, 2020, <doi:10.1038/s41562-020-0912-z>) or multiverse analyses (Steegen, Tuerlinckx, Gelman & Vanpaemel, 2016, <doi:10.1177/1745691616658637>) including functions to setup, run, evaluate, and plot all specifications, as well as to conduct inference on the specification curve based on resampling under the null.
