Get reported crimes since 2014 for a specific area.

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().
