plot.pointPairs {gstat}R Documentation

Plot a point pairs, identified from a variogram cloud

Description

Plot a point pairs, identified from a variogram cloud

Usage

## S3 method for class 'pointPairs':
plot(x, data, xcol = data$x, ycol = data$y, xlab = "x coordinate", 
ylab = "y coordinate", col.line = 2, line.pch = 0, main = "selected point pairs", ...) 

Arguments

x object of class "pointPairs", obtained from the function plot.variogramCloud, 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
line.pch if non-zero, symbols are also plotted at the middle of line segments, to mark lines too short to be visible on the plot; the color used is col.line; the value passed to this argument will be used as plotting symbol (pch)
main title of plot
... arguments, further passed to xyplot

Value

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

Examples

### The following requires interaction, and is therefore outcommented
#data(meuse)
#coordinates(meuse) = ~x+y
#vgm1 <- variogram(log(zinc)~1, meuse, cloud = TRUE)
#pp <- plot(vgm1, id = TRUE)
### Identify the point pairs
#plot(pp, data = meuse) # meuse has x and y as coordinates
