The Human and Financial Costs of Severe Weather in the USA
A data cleaning project of The National Oceanic and Atmospheric Administration database. They define 48 types of storms but there are more than 400 unique values for storm type in the database. I use regular expressions and logical statements to efficiently clean these data into a true factor variable with a limited number of levels. Then I create a visualization to show the number of injuries and fatalities and the financial costs of storm types in the USA.
