panel functions for most of the variogram plots through lattice

Description

Variogram plots contain symbols and lines; more control over them can be gained by writing your own panel functions, or extending the ones described here; see examples.

Usage

vgm.panel.xyplot(x, y, subscripts, type = "p", pch = plot.symbol$pch, 
    col, col.line = plot.line$col, col.symbol = plot.symbol$col, 
    lty = plot.line$lty, cex = plot.symbol$cex, ids, lwd = plot.line$lwd, 
    model = model, direction = direction, labels, shift = shift, mode = mode, ...) 
panel.pointPairs(x, y, type = "p", pch = plot.symbol$pch, col, col.line = 
	plot.line$col, col.symbol = plot.symbol$col, lty = plot.line$lty, 
	cex = plot.symbol$cex, lwd = plot.line$lwd, pairs = pairs, 
	line.pch = line.pch, ...) 

Arguments

x	x coordinates of points in this panel
y	y coordinates of points in this panel
subscripts	subscripts of points in this panel
type	plot type: "l" for connected lines
pch	plotting symbol
col	symbol and line color (if set)
col.line	line color
col.symbol	symbol color
lty	line type for variogram model
cex	symbol size
ids	gstat model ids
lwd	line width
model	variogram model
direction	direction vector c(dir.horizontal, dir.ver)
labels	labels to plot next to points
shift	amount to shift the label right of the symbol
mode	to be set by calling function only
line.pch	symbol type to be used for point of selected point pairs, e.g. to highlight point pairs with distance close to zero
pairs	two-column matrix with pair indexes to be highlighted
...	parameters that get passed to lpoints

Value

ignored; the enclosing function returns a plot of class trellis
