Usage

get_area_crime(
  area,
  description = NULL,
  date_range = NULL,
  where = NULL,
  dist = NULL,
  diag_ratio = NULL,
  asp = NULL,
  unit = "m",
  trim = FALSE,
  crs = pkgconfig::get_config("mapbaltimore.crs", 2804)
)

Arguments

area	sf, sfc, or bbox object. If multiple areas are provided, they are unioned into a single sf object using sf::st_union().
description	Crime type or description. Supported options include "AGG. ASSAULT", "ARSON", "AUTO THEFT", "BURGLARY", "COMMON ASSAULT", "HOMICIDE", "LARCENY", "LARCENY FROM AUTO", "RAPE", "ROBBERY - CARJACKING", "ROBBERY - COMMERCIAL", "ROBBERY - RESIDENCE", "ROBBERY - STREET", or "SHOOTING". Not case sensitive.
date_range	Date range as character vector in format of c("YYYY-MM-DD", "YYYY-MM-DD"). Minimum and maximum values are used if length is greater than 1.
where	where query string passed to esri2sf, Default: NULL
dist	buffer distance in units. Optional.
diag_ratio	ratio of diagonal distance of area's bounding box used as buffer distance. e.g. if the diagonal distance is 3000 meters and the "diag_ratio = 0.1" a 300 meter will be used. Ignored when dist is provided.
asp	Aspect ratio of width to height as a numeric value (e.g. 0.33) or character (e.g. "1:3"). If numeric, get_asp() returns the same value without modification.
unit	Units for buffer. Supported options include "meter", "foot", "kilometer", and "mile", "nautical mile" Common abbreviations (e.g. "km" instead of "kilometer") are also supported. Distance in units is converted to units matching GDAL units for x; defaults to "meter"
trim	If TRUE, x is trimmed to y with st_trim().
crs	Cordinate reference system to return, Default: 4326 for sf_to_df() and NULL for df_to_sf().
