poisbinom: A Faster Implementation of the Poisson-Binomial Distribution (with Santiago Olivella, 2017-) provides the probability, distribution, and quantile functions and random number generator for the Poisson-Binomial distribution.

endorse: Bayesian Measurement Models for Analyzing Endorsement Experiments (with Kosuke Imai and Bryn Rosenfeld, 2012-) fits the hierarchical and non-hierarchical Bayesian measurement models proposed by Bullock, Imai, and Shapiro (2011) <doi:10.1093/pan/mpr031> to analyze endorsement experiments.
