I'm trying to create a Choropleth of a county using tracts as units.
Where it says "state_name", I have no idea what to put.
I've tried OH, OHIO, and the FIPS codes.
tract_choropleth(df, ohio, title = "census", legend = "",)
Each result ends with "Error in state_name %in% state.regions$region : object 'ohio' not found"
The format for the names is a lower-case string. But it must be a string. The sample code has the unquoted ohio, so R is trying to interpret it as a variable name. Just quoting the string will make it work.
