Attach Geometry to MCCD Data

Join LGD boundary geometries to a data frame containing a State column. Returns an sf object suitable for ggplot2::geom_sf().

Usage

attach_geometry(data, geography = NULL)

Arguments

data

A data frame with a State column.

geography

One of "state" or "district". If NULL, auto-detected from column names. MCCD data is state-level; use "district" when joining with CRS district data.

Value

An sf object with geometry attached. Non-geographic entries ("All States (Total)", "Unknown") are dropped.

Examples

if (FALSE) { # \dontrun{
deaths <- get_mccd("cause", sex = "T", year = 2020)
deaths_sf <- attach_geometry(deaths)
ggplot(deaths_sf) +
  geom_sf(aes(fill = Deaths))
} # }
