Plot exposure data.

Usage

plot_exposure(
  exposure,
  region_boundary,
  group_boundary = NULL,
  chem_label = "chnm",
  ncol = 2
)

Arguments

exposure: list of exposure data named by region label.
region_boundary: "sf" data.frame mapping features to a "geometry" column. Used to color regions.
group_boundary: (optional) "sf" data.frame containing a "geometry" column. Used to draw outlines.
chem_label: label for facet_wrap.
ncol: number of columns to wrap.

Value

ggplot2 object.

Examples

# Load package data
exposure <- split(geo_tox_data$exposure, ~FIPS)
region_boundary <- geo_tox_data$boundaries$county
group_boundary <- geo_tox_data$boundaries$state

# Plot county exposure data
# Use CASN as label to avoid long chemical names
plot_exposure(exposure,
              region_boundary,
              chem_label = "casn",
              ncol = 5)


# Add state boundaries
plot_exposure(exposure,
              region_boundary,
              group_boundary = group_boundary,
              chem_label = "casn",
              ncol = 5)
