plotpolys: Plot polygons

Description

A helper function for plotting polygons in a global bounding box. get.polylist() is a simple function to make imported GIS vector polygons into a "polylist" object from a "Map" object; convert.pl() serves to convert the deprecated "multipart" "polylist" format to an NA-separated format now used by plotpolys and poly2nb

Usage

plotpolys(pl, bb, col = NA, border = par("fg"), add = FALSE, xlim, ylim)
get.polylist(Map, region.id=NULL)
convert.pl(pl)

Arguments

pl

list of polygons of class polylist

bb

matrix of polygon bounding boxes - columns are LL(x), LL(y), UR(x), UR(y)

col

colurs to use for filling the polygons

border

the color to draw the border

add

add to existing plot

xlim, ylim

numeric of length 2, giving the x and y coordinates ranges

Map

object of class Map, imported from a GIS polygon vector file using unpublished package "maptools"

region.id

character vector of region ids to be added to the neighbours list as attribute region.id
