plot.point.pairs {gstat} | R Documentation |
Plot a point pairs, identified from a variogram cloud
plot.point.pairs(x, data, xcol = data$x, ycol = data$y, xlab = "x coordinate", ylab = "y coordinate", col.line = 2, ...)
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 |
col.line |
color for lines connecting points |
... |
arguments, further passed to xyplot |
plots the data locations, with lines connecting the point pairs identified (and refered to by indices in) x

### The following requires interaction, and is therefore outcommented #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
