\format{
This data frame contains the following columns:
       \itemize{
               \item{AREA} {computed by ArcView}
               \item{PERIMETER} {computed by ArcView}
               \item{COLUMBUS_} {internal polygon ID (ignore)}
               \item{COLUMBUS_I} {another internal polygon ID (ignore)}
               \item{POLYID} {yet another polygon ID}
               \item{NEIG} {neighborhood id value (1-49);
                       conforms to id value used in Spatial Econometrics book.}
               \item{HOVAL} {housing value (in 1,000 USD)}
               \item{INC} {household income (in 1,000 USD)}
               \item{CRIME} {residential burglaries and vehicle thefts per thousand
                       households in the neighborhood}

               \item{PLUMB} {percentage housing units without plumbing}
               \item{DISCBD} {distance to CBD}
               \item{X} {x coordinate (in arbitrary digitizing units, not polygon coordinates)}

\description{
The \code{columbus} data frame has 49 rows and 22 columns. Unit of analysis: 49 neighbourhoods in Columbus, OH, 1980 data. In addition the data set includes a \code{polylist} object \code{polys} with the boundaries of the neighbourhoods, a matrix of polygon centroids \code{coords}, and \code{col.gal.nb}, the neighbours list from an original GAL-format file. The matrix \code{bbs} is DEPRECATED, but retained for other packages using this data set.
}
\details{
The row names of \code{columbus} and the \code{region.id} attribute of \code{polys} are set to \code{columbus$NEIGNO}.
