Like most R Programmers, I’m a fan of the R packages that RStudio develops. They recently announced Flexdashboards: Easy interactive dashboards written in RMarkdown. I’m always trying to expand my R skills with side projects so I’ve put together a Flexdashboard to visualize USA zipcodes on a choropleth map and a shiny dropdown to dynamically switch States. A choropleth map is a shaded map to show numerical variations such as population density.
These are the general steps of the project:
- Locate and download shapefiles from www2.census.gov
- Locate and download zipcode data which contain corresponding zipcodes, city, county and demographic information about estimated population
- Clean and format the zipcode data and merge with the shapefile data object
- Create a choropleth map with the htmlwidget: leaflet
Let me know what you think!
