image.logratioVariogramAnisotropy: Plot variogram maps for anisotropic logratio variograms

In gmGeostats: Geostatistics for Compositional Analysis

Plot variogram maps for anisotropic logratio variograms

Description

Image method to obtain variogram maps for anisotropic logratio variograms

Usage

## S3 method for class 'logratioVariogramAnisotropy'
image(
  x,
  jointColor = FALSE,
  breaks = NULL,
  probs = seq(0, 1, 0.1),
  col = spectralcolors,
  ...
)

Arguments

x	object of class c("logratioVariogramAnisotropy", "logratioVariogram")
jointColor	logical, should all variogram maps share the same color scale?
breaks	breaks to use in the color scale
probs	alternatively to explicit breaks, these probabilities allow to ask for some equally probable breaks
col	either a color palette, or else a vector of colors to use, of length length(breaks)-1
...	additional arguments for generic functionality (currently ignored)

Value

This function is called for its effect of producing a figure. Additionally, the graphical parameters active prior to calling this function are returned invisibly.

Examples

data("jura", package="gstat")
X = jura.pred[,1:2]
Zc = compositions::acomp(jura.pred[,7:9])
vg = logratioVariogram(data=Zc, loc=X, azimuth=c(0:18)*10, 
                           azimuth.tol=22.5)
image(vg)
image(vg, jointColor=TRUE)
