SpatialRings: create objects of class SpatialRings or SpatialRingsDataFrame

Description

create objects of class SpatialRings or SpatialRingsDataFrame from lists of Srings objects and data.frames

Usage

Sring(coords, proj4string=CRS(as.character(NA)), hole=as.logical(NA))
Srings(srl, ID)
SpatialRings(Srl, pO = 1:length(Srl))
SpatialRingsDataFrame(Sr, data, match.ID = TRUE)

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 ring as hole or not

srl

list with Sring-class objects

ID

character vector of length one with identifier

Srl

list with objects of class Srings-class

pO

integer vector; plotting order

Sr

object of class SpatialRings-class

data

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

match.ID

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

Value

• Sring returns an object of class Sring; Srings returns an object of class Srings; SpatialRings returns object of class SpatialRings; SpatialRingsDataFrame returns object of class SpatialRingsDataFrame
