Keywords
spatial
Usage
readSplus(file, proj4string = CRS(as.character(NA)))
Arguments
file
name of file
proj4string
Object of class '"CRS"'; holding a valid proj4 string
Value

• readSplus returns a SpatialPolygons object

Note

In the example, taken from the GeoBUGS manual, the smaller part of area1 has a counter-clockwise ring direction in the data, while other rings are clockwise. This implies that it is a hole, and does not get filled. Errant holes may be filled using checkPolygonsHoles. The region labels are stored in the ID slots of the Polygons objects.
