Notes
There are three ways to get data from the CDC:
- Downloadable files (for example)
- Wonder web application
- Wonder API x
The data available in each is not identical. Geographical data is only available through the Wonder web application, where it is suppressed in some cases for purposes of anonymity. It is not available through the API (see "More about WONDER API queries" here for more info), nor the downloadable files.
There are many variables (such as paternity variables) in the downloadable files that are not available through web application nor the Wonder API.
The wondr package makes life a little easier but does not remove the challenge of setting up the queries, and the documentation is very scant. The API queries closely match the web application, so understanding it is key to understanding how to set up a query.
