Examples
an object ’pixmap’ displayed in the map background
a data frame with 4 columns to plot the contour of the map : each row gives a
segment (x1,y1,x2,y2)
a data frame of class ’area’ to plot a set of surface units in contour
if TRUE uses the current graphics window
if (require(splancs, quiet = TRUE)){
wxy=data.frame(expand.grid(-3:3,-3:3))
names(wxy)=c("x","y")
z=(1/sqrt(2))*exp(-(wxy$x^2+wxy$y^2)/2)
par(mfrow=c(2,2))
s.value(wxy,z)
s.image(wxy,z)
s.image(wxy,z,kgrid=5)
s.image(wxy,z,kgrid=15)
