This analysis uses the NOAA Storm Events database (1950 through November 2011) to identify which event types cause the greatest harm to population health (fatalities + injuries) and which cause the largest economic damage (property + crop losses). The R Markdown document downloads the raw compressed CSV, performs reproducible processing (including interpreting damage exponent codes), summarizes the data by event type, and presents bar charts of the top contributors for both public-health and economic impact. Code is shown for every step so the analysis can be re-run and published to RPubs.
