Produce h-scatterplot — hscat • gstat

Produces h-scatterplots, where point pairs having specific separation distances are plotted. This function is a wrapper around xyplot.

Usage

hscat(formula, data, breaks, pch = 3, cex = .6, mirror = FALSE, 
  variogram.alpha = 0, as.table = TRUE,...)

formula: specifies the dependent variable
data: data where the variable in formula is resolved
breaks: distance class boundaries
pch: plotting symbol
cex: plotting symbol size
mirror: logical; duplicate all points mirrored along x=y? (note that correlations are those of the points plotted)
variogram.alpha: parameter to be passed as alpha parameter to variogram; if alpha is specified it will only affect xyplot by being passed through ...
as.table: logical; if TRUE, panels plot top-to-bottom
...: parameters, passed to variogram and xyplot

an object of class trellis; normally the h scatter plot

Data pairs are plotted once, so the h-scatterplot are not symmetric.
