The infu2 package is the Bayesian couterpart and has been developed for use with brms. It works with population-level or group-level effects, the Bayesian equivalents of fixed-effects and random-effects. It contains functions for extracting coefficients, calculating the influence of terms, generating CDI plots, step plots, and other diagnostic plots.
