Note that the interactive plots displayed in this slide deck may not render well (if at all) in Firefox. Chrome and Safari appear to be unaffected by this issue (though this has not been thoroughly tested). YMMV.
This repository contains a slide deck entitled "Twitter-based Alerts of Major Disasters," which was presented in UC Berkeley's Biomedical Big Data seminar on 13 November 2017. The deck was built using the R package xaringan, with support from knitr, R Markdown, and pandoc.
The file for the main deck is index.html, built from the RMarkdown file index.Rmd. To recompile in R:
# install.packages("rmarkdown")
library(rmarkdown)
render("index.Rmd")
browseURL("index.html")
