| SpatialPolygons {sp} | R Documentation |
create objects of class SpatialPolygons or SpatialPolygonsDataFrame from
lists of Polygons objects and data.frames
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)
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 |
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.
