xyplot.evgram: Plot 'evgram' object

In gear: Geostatistical Analysis in R

Description

Plots evgram object produced by the evgram function using the xyplot function. Note: the lattice package must be loaded (i.e., library(lattice) or lattice::xyplot must be specifically called for this function to work. See Examples.

Usage

xyplot.evgram(x, ..., split = FALSE)

Arguments

x	An evgram object produced by the evgram function.
...	Additional arguments to pass the xyplot function to change aspects of the plot.
split	A logical value indicating whether, for a directional semivariogram, the directional semivariograms should be displayed in a single or split panels. Default is FALSE, for a single panel.

Examples

v = evgram(Al ~ 1, co, ~ easting + northing)
if (requireNamespace("lattice")) {
   lattice::xyplot(v)

v2 = evgram(Al ~ 1, co, ~ easting + northing, angle = 22.5, ndir = 4)
if (requireNamespace("lattice")) {
   lattice::xyplot(v2)
   # show how attributes can be changed using different
   # arguments available in lattice::xyplot.
   lattice::xyplot(v2, col = 2:5)
