Clips the interstates and cities datasets to the bounding box of the map and plots them.
Usage
stat_cities(
mapping = NULL,
data = NULL,
geom = ggplot2::GeomSf,
position = "identity",
na.rm = FALSE,
adjust = 1,
min_pop = 1e+05,
show.legend = NA,
inherit.aes = TRUE,
...
)
stat_interstates(
mapping = NULL,
data = NULL,
geom = ggplot2::GeomSf,
position = "identity",
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE,
...
)Arguments
- mapping
Set of aesthetic mappings created by
aes()- data
The data to be displayed in this layer
- geom
The geometric object to use display the data
- position
Position adjustment
- na.rm
if
TRUE, will silently remove missing values from calculations- adjust
A multiplicative scaling factor for the default label sizes
- min_pop
The minimum population a city must have had in 2006 to be shown.
- show.legend
Should this layer be included in the legends?
- inherit.aes
If
FALSE, overrides the default aesthetics, rather than combining with them.- ...
Passed onto the underlying geoms.
Examples
