Plots the empirical variogram for longitudinal data
Description
Plots the empirical variogram for observed measurements, of an
object of class vargm
, obtained by using function
variogram
.
Usage
## S3 method for class 'vargm'
plot(x, smooth = FALSE, bdw = NULL, follow.time = NULL, points = TRUE, ...)
Arguments
