In harveybarnhard/smoov: Simple Mapping of our Vicinities

Description

Simple mapping tool

Usage

smoov(
  geo,
  data = NULL,
  value = NULL,
  id = "fips",
  year = 2010,
  detailed = FALSE,
  class = "sf",
  states = NULL,
  counties = NULL,
  tracts = NULL,
  ...
)

Arguments

geo	Character string; Provide level of map geography e.g. county. See details.
data	Dataframe; ID columns matching the level of geography. See details.
value	character; Name of the column in data with which a choropleth is created. If no column is provided, a map of boundaries is produced. If more than one value is inputted, a faceted map is created.
id	character; "fips" by default. Name of the column in data that provides the relevant geography identifier (e.g. FIPS code).
year	integer; Currently either 2000 or 2010. Year of census geography. The most recent year by default.
detailed	logical; FALSE by default. If TRUE, then more detailed geographies are used when available
class	"sp" or "sf"; "sf" by default.
...	Optional aesthetic parameters, subsetting parameters. See details below.

Value

Output will be a `ggplot` base layer onto which any `ggplot` layer may
be added. 

Geographic Subsetting Parameters

• states: Vector of state FIPS codes. Character and numeric vectors allowed.

• counties: Vector of county FIPS codes. Character and numeric vectors allowed. If length of states vector is longer than one, then counties vector must be of the same length.

• tracts: Vector of tract FIPS codes. Character and numeric vectors allowed. If length of states vector or counties vector islonger than one, then tracts vector must be of the same length as counties vector.

Aesthetic Parameters

• gradient: The color gradient to be plotted, currently only "redblue"

• gradient_dir: The direction the color gradient should go. Default is 1 for low values to get the first value of the gradient and -1 is for low values to get the second value of the color gradient.

• gradient_breaks: A vector of five probabilities in [0,1]^5 that define the quantiles of values that the gradient emphasizes. Defaults to c(0,0.35,0.5,0.65,1)

• linesize: The size of the borders of geographic units. Defaults to 0.05 for plotting tracts, 0.1 for other levels of geography

• alpha: Transparency parameter for fill colors. 0 is completely transparent and 1 is completely opaque. Defaults to 0.9

• bordercolor: Color of geography borders
