The function outputs a SpatialPolygonsDataFrame object to be used by Mondrian

sp2Mondrian(SP, file, new_format=TRUE)

Arguments

SP

a SpatialPolygonsDataFrame object

file

file where output is written

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)

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.

Examples

if (FALSE) { td <- tempdir() xx <- readShapePoly(system.file("shapes/columbus.shp", package="maptools")[1]) sp2Mondrian(xx, file=file.path(td, "columbus1.txt")) xx <- readShapePoly(system.file("shapes/sids.shp", package="maptools")[1]) sp2Mondrian(xx, file=file.path(td, "sids1.txt")) }
