s.Spatial: Mapping of a Spatial* object

In sdray/adegraphics: An S4 Lattice-Based Package for the Representation of Multivariate Data

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, scale = TRUE, 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)
scale	a logical indicating if numeric variables should be scaled
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 without data
g1 <- s.Spatial(elec88$Spatial)

## Not run: 
  if(require(sp, quietly = TRUE)) {
    ## mapping with data
    obj <- SpatialPolygonsDataFrame(Sr = elec88$Spatial, data = elec88$tab)
    g2 <- s.Spatial(obj)
    g3 <- s.Spatial(obj, nclass = 2, col = c("red", "blue"))
  }

## End(Not run)
