s.Spatial: Mapping of a Spatial* object

Description

This function represents a background map linked with data or not.

Usage

s.Spatial(spObj, col = TRUE, nclass = 5, plot = TRUE, 
  storeData = TRUE, pos = -1, ...)

Arguments

spObj

an object deriving from class Spatial (package sp)

col

a logical or a color to fill the background color of spObj

nclass

if spObj contains data, the desired number of intervals splitting the data (using pretty)

plot

a logical indicating if the graphics is displayed

storeData

a logical indicating if the data should be stored in the returned object. If FALSE, only the names of the data arguments are stored

pos

an integer indicating the position of the environment where the data are stored, relative to the environment where the function is called. Useful only if storeData is FALSE

...

additional graphical parameters (see adegpar and trellis.par.get)

Value

• An object of class ADEg (subclass S2.label) or ADEgS (if spObj contains more than one column ). The result is displayed if plot is TRUE.

Examples

data(elec88, package = "ade4")
## mapping whithout data
g1 <- s.Spatial(elec88$Spatial)

if(require(sp, quiet = TRUE)) {
    ## mapping whith data
    obj <- SpatialPolygonsDataFrame(Sr = elec88$Spatial, data = elec88$tab)
    g2 <- s.Spatial(obj)
    g3 <- s.Spatial(obj, nclass = 2, col = c("red", "blue"))
