The finished app can be found here. A full write up of this project can be accessed via this link.
The contents of this main folder are the shiny R source files (global, server and ui files). The folders are img (images used in shiny application) and cleaned_data (data used for analysis in app and blog post).
The key packages used for this project are:
- Shiny - overall framework
- dplyr - data manipulation and preparation
- plotly - prettifying ggplots and making them interactive
- leaflet - showing the city-sized craters created by meteor impacts
There are some cool helper functions in global.R that I wrote to create elliptical orbits in ggplot2 given an objects orbital parameters 'a' and 'q'. Server.R contains code for the interactive crater application.
