Perform Common JavaScript Operations in Shiny Apps using Plain R Code (shinyjs)
Perform common JavaScript operations in Shiny applications without having to know any JavaScript. Many useful JavaScript functions are made available by shinyjs with a simple R interface so that you don’t have to write any JavaScript code. Even if you do know JavaScript, shinyjs can be used as convenience functions to avoid dealing with message passing and writing JavaScript code.

Integrated Nested Laplace Approximation (INLA)
The R inla packages solves models using Integrated nested Laplace approximation (INLA) which is a new approach to statistical inference for latent Gaussian Markov random field (GMRF) models described in. In short, a latent GMRF model is a hierarchical model where, at the first stage we find a distributional assumption for the observables y usually assumed to be conditionally independent given some latent parameters and, possibly, some additional parameters.

Bayesian Cost Effectiveness Analysis (BCEA)
Produces an economic evaluation of a Bayesian model in the form of MCMC simulations. Given suitable variables of cost and effectiveness / utility for two or more interventions, BCEA computes the most cost-effective alternative and produces graphical summaries and probabilistic sensitivity analysis.
