area: A function to compute the spatial units' areas
Usage
area(spatobj = NULL, folder = NULL, shape = NULL)
Arguments
spatobj
- a Spatial object (SpatialPolygonsDataFrame)
folder
- a character vector with the folder (directory)
where the shapefile is
shape
- a character vector with the name of the shapefile
(without the .shp extension)
Value
A vector with spatial units'areas.
}
description{
The function is based on pkg{rgdal} package and
can be used by providing a shape file or a R spatial object
(SpatialPolygonsDataFrame).
