An interactive Shiny app to learn about Hamiltonian Monte Carlo sampling.

This is still a work in progress. I do have a couple of ideas to try and I would like to document everything a bit more. Suggestions are more than welcomed :)

Install this package from GitHub with:

# install.packages("devtools")
devtools::install_github("tomicapretto/shiny-hmc")

The function run_app() fires up the application. Just do

shinyhmc::run_app()

and have fun!

• Add content about each target distribution in the main container
• Change color of segments as more segments are added?
  • To make clear when a trajectory returns over the same point
  • Gradient instead of transparency?
• Allow users to specify a momentum

• Show what happens when momentum is null (i.e. c(0, 0))
• Show what happens when momentum is huge (e.g. c(4, 3.5))
• Show what happens when momentum is exactly the same in both directions (c(2, 2))
