lines.variogram

Line with a Empirical Variogram

A sample (empirical) variogram computed using the function variog is added to the current plot.

## S3 method for class 'variogram'
lines(x, max.dist, type = "o",  scaled = FALSE,
         pts.range.cex, ...)

`x`	an object of the class `"variogram"`, typically an output from the function `variog`.
`max.dist`	maximum distance for the x-axis. By default takes the maximum distance for which the sample variogram was computed.
`type`	type of line for the empirical variogram. The default is `"o"` (dots and lines). See documentation for `lines` for further details.
`scaled`	logical. If `TRUE` the variogram values are divided by the sample variance. This allows comparison between variograms of different variables.
`pts.range.cex`	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 `lines`.

A line with the empirical variogram is added to the plot in the current graphics device. No values are returned.
