- regions
The region breakdown for the map, can be one of
("states"
, "state"
, "counties"
, "county"
).
The default is "states"
.
- include
The regions to include in the resulting map. If regions
is
"states"
/"state"
, the value can be either a state name, abbreviation or FIPS code.
For counties, the FIPS must be provided as there can be multiple counties with the
same name. If states are provided in the county map, only counties in the included states
will be returned.
- exclude
The regions to exclude in the resulting map. If regions
is
"states"
/"state"
, the value can be either a state name, abbreviation or FIPS code.
For counties, the FIPS must be provided as there can be multiple counties with the
same name. The regions listed in the include
parameter are applied first and the
exclude
regions are then removed from the resulting map. Any excluded regions
not present in the included regions will be ignored.
- data
A data frame containing values to plot on the map. This
parameter should be a data frame consisting of two columns,
a FIPS code (2 characters for state, 5 characters for county)
and the value that should be associated with that region. The
columns of data
must be fips
or state
and
the value of the values
parameter.
- values
The name of the column that contains the values to be associated
with a given region. The default is "value"
.
- theme
The theme that should be used for plotting the map. The default
is theme_map
from ggthemes.
- labels
Whether or not to display labels on the map. Labels are not displayed

option in the ggplot2::aes()
mapping. The default is "black"
.

Other arguments to pass to ggplot2::aes()
. These are
often aesthetics, used to set an aesthetic to a fixed value, like color = "red"
or linewidth = 3
. They affect the appearance of the polygons used to render
the map (for example fill color, line color, line thickness, etc.). If any of
color
/colour
, fill
, or linewidth
are not specified they
are set to their default values of color="black"
, fill="white"
,
and linewidth=0.4
.
