SpatialPolygons: create objects of class SpatialPolygons or SpatialPolygonsDataFrame

Description

create objects of class SpatialPolygons or SpatialPolygonsDataFrame from lists of Polygons objects and data.frames

Usage

Polygon(coords, hole=as.logical(NA))
Polygons(srl, ID)
SpatialPolygons(Srl, pO, proj4string=CRS(as.character(NA)))
SpatialPolygonsDataFrame(Sr, data, match.ID = TRUE)
getSpatialPolygonsLabelPoints(SP)

Arguments

coords

2-column numeric matrix with coordinates; first point (row) should equal last coordinates (row)

proj4string

projection string of class CRS-class

hole

logical value for setting polygon as hole or not

srl

list with Polygon-class objects

ID

character vector of length one with identifier

Srl

list with objects of class Polygons-class

pO

integer vector; plotting order; if missing in reverse order of Polygons area

Sr

object of class SpatialPolygons-class

data

object of class data.frame; the number of rows in data should equal the number of Polygons-class objects in Sr

match.ID

logical: (default TRUE): match SpatialPolygons member Polygons ID slot values with data frame row names, and re-order the data frame rows if necessary

SP

object of class SpatialPolygons-class

Value

• Polygon returns an object of class Polygon; Polygons returns an object of class Polygons; SpatialPolygons returns object of class SpatialPolygons; SpatialPolygonsDataFrame returns object of class SpatialPolygonsDataFrame getSpatialPolygonsLabelPoints returns an object of class SpatialPoints with label points.
