## Columbus OH spatial analysis data set - old numbering

### Description

The `COL.OLD` data frame has 49 rows and 22 columns. The observations are ordered and numbered as in the original analyses of the data set in the SpaceStat documentation and in Anselin, L. 1988 Spatial econometrics: methods and models, Dordrecht: Kluwer. Unit of analysis: 49 neighbourhoods in Columbus, OH, 1980 data. In addition the data set includes a `polylist` object `polys.OLD` with the boundaries of the neighbourhoods, a matrix of polygon centroids `coords.OLD`, and `COL.nb`, the neighbours list as used in Anselin (1988).

### Usage

    data(oldcol)

### Format

This data frame contains the following columns:

AREA
  computed by ArcView
PERIMETER
  computed by ArcView
COLUMBUS.
  internal polygon ID (ignore)
COLUMBUS.I
  another internal polygon ID (ignore)
POLYID
  yet another polygon ID
NEIG
  neighborhood id value (1-49); conforms to id value used in Spatial Econometrics book.
HOVAL
  housing value (in $1,000)
INC
  household income (in $1,000)
CRIME
  residential burglaries and vehicle thefts per thousand households in the neighborhood
OPEN
  open space in neighborhood
PLUMB
  percentage housing units without plumbin
DISCBD
  distance to CBD
X
  x coordinate (in arbitrary digitizing units, not polygon coordinates)
Y
  y coordinate (in arbitrary digitizing units, not polygon coordinates)
AREA
  neighborhood area (computed by SpaceStat)
NSA
  north-south dummy (North=1)
NSB
  north-south dummy (North=1)
EW
  east-west dummy (East=1)
CP
  core-periphery dummy (Core=1)
THOUS

NEIGNO
  NEIG+1,000, alternative neighborhood id value
PERIM
  polygon perimeter (computed by SpaceStat)

### Details

The row names of `COL.OLD` and the `region.id` attribute of `COL.nb` are set to `columbus$NEIGNO`.
