Chicago Crime Data

This dataset is a record of spatial locations of crimes reported in the period 25 April to 8 May 2002, in an area of Chicago (Illinois, USA) close to the University of Chicago. The original crime map was published in the Chicago Weekly News in 2002.

The data give the spatial location (street address) of each crime report, and the type of crime. The type labels are interpreted as follows:

`assault`	battery/assault
`burglary`	burglary
`cartheft`	motor vehicle theft
`damage`	criminal damage
`robbery`	robbery
`theft`	theft
`trespass`	criminal trespass

All crimes occurred on or near a street. The data give the coordinates of all streets in the survey area, and their connectivity.

The dataset chicago is an object of class "lpp" representing a point pattern on a linear network. See lpp for further information on the format.

These data were published and analysed in Ang, Baddeley and Nair (2012).
