plot.point.pairs: Plot a point pairs, identified from a variogram cloud

Description

Plot a point pairs, identified from a variogram cloud

Usage

plot.point.pairs(x, data, xcol = data$x, ycol = data$y, xlab = "x coordinate", 
ylab = "y coordinate", ...)

Arguments

x

object of class "point.pairs", obtained from the function plot.variogram.cloud, containing point pair indices

data

data frame to which the indices refer (from which the variogram cloud was calculated)

xcol

numeric vector with x-coordinates of data

ycol

numeric vector with y-coordinates of data

xlab

x-axis label

ylab

y-axis label

...

arguments passed to xyplot

Value

• plots the data locations, with lines connecting the point pairs identified (and refered to by indices in) x

Examples

#data(meuse)
#vgm1 <- variogram(log(zinc)~1, ~x+y, meuse, cloud = TRUE)
#pp <- plot(vgm1, id = TRUE)
# identify the point pairs
#plot(pp, data = meuse) # meuse has x and y as coordinates
