600. gsDesign: Group Sequential Design- Generates group sequential designs using alpha- and beta-spending functions or Wang-Tsiatis (e.g., O'Brien-Fleming and Pocock) boundary families. Many plotting capabilities as well as non-binding futility rules are available. Easily extended.
603. Multiple Cue Probability Learning- mcplR offers a flexible (S4) framework to investigate multiple cue probability learning (MCPL). mcplR incorporates a number of learning models (Rescorla-Wagner, GCM, ALCOVE, etc) in a general state-space framework, where new models can be easily added.
607. RColony- The RColony package provides tools for the implementation of the Colony pedigree analysis software. In addition it provides tools for visualising, and summarising the results of the Colony analyses.
608. splinesurv- A package containing utilities for nonparametric Bayesian analysis of clustered survival data. The baseline hazard function and frailty density are modeled using penalized B-splines. Regression and spline parameters are estimated via MCMC.
