Line with a Empirical Variogram
A sample (empirical) variogram computed using the
variog is added to the current plot.
# S3 method for variogram lines(x, max.dist, type = "o", scaled = FALSE, pts.range.cex, …)
an object of the class
"variogram", typically an output from the function
maximum distance for the x-axis. By default takes the maximum distance for which the sample variogram was computed.
type of line for the empirical variogram. The default is
"o"(dots and lines). See documentation for
linesfor further details.
TRUEthe variogram values are divided by the sample variance. This allows comparison between variograms of different variables.
optional. A two elements vector with maximum and minimum values for the caracter expansion factor
cex. If provided the point sizes in binned variogram are proportional to the number of pairs of points used to compute each bin.
other arguments to be passed to the function
A line with the empirical variogram is added to the plot in the current graphics device. No values are returned.
