draw.color {RGeostats}R Documentation

Color representation

Description

Color representation

Usage

draw.color(x, y, z, elev, zmin = NA, zmax = NA, col = NA, bg=NA, pch = 21,
           pos.legend = 0, ...)

Arguments

x

Array giving the coordinates of the samples along X

y

Array giving the coordinates of the samples along Y

z

Array giving the target variable

elev

Array giving the values of the samples (only used for RGL representation)

zmin

Minimum acceptable value for the target variable.

zmax

Maximum acceptable value for the target variable.

col

Color of the symbol (foreground) for the samples whose target variable lies within the bounds.

bg

Color of the symbol background for the samples whose target variable lies within the bounds.

pch

Symbol type for representing for samples

pos.legend

Position of the optional legend. See legend.locate for details.

Examples

# We define a data base and perform a Kriging (exact interpolator) on a regular grid.
# Then we represent the interpolated value together with the conditioning dat, using the same color

set.seed(1223421)
data  = db.create(x1=floor(100.*runif(100)),
                  x2=floor(100.*runif(100)),z1=runif(100))
grid  = db.create(nx=c(100,100))
model = model.create(2,range=30)
neigh = neigh.create(type=0,ndim=2)
grid  = kriging(data,grid,model,neigh)
rg    = range(grid[,"*estim"],na.rm=TRUE)

plot(grid,zlim=rg)
plot(data,name.color="z1",add=TRUE,cex=1.5,fg="black",zmin=rg[1],zmax=rg[2])
