\name{sp2Mondrian}
\alias{sp2Mondrian}
%- Also NEED an '\alias' for EACH other topic documented here.
\title{write map data for Mondrian}
\description{
The function outputs a SpatialPolygonsDataFrame object to be used by Mondrian
}
\usage{
sp2Mondrian(SP, file, new_format=TRUE)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{SP}{a SpatialPolygonsDataFrame object}
\item{file}{file where output is written}
\item{new_format}{default TRUE, creates a text data file and a separate map file; the old format put both data sets in a single file - the map file is named by inserting "MAP\_" into the file= argument after the rightmost directory separator (if any)}
}

\author{Patrick Hausmann and Roger Bivand}
\note{
At this release, the function writes out a text file with both data and polygon(s) identified as belonging to each row of data.

\dontrun{
xx <- readShapePoly(system.file("shapes/columbus.shp", package="maptools")[1])
sp2Mondrian(xx, file="columbus1.txt")
xx <- readShapePoly(system.file("shapes/sids.shp", package="maptools")[1])
sp2Mondrian(xx, file="sids1.txt")
