svar.plot: Plot a semivariogram object

In npsp: Nonparametric Spatial Statistics

Plot a semivariogram object

Description

Utilities for plotting pilot semivariograms or fitted models.

plot.fitsvar plots a fitted variogram model.

plot.svar.bin plots the binned semivariances.

plot.np.svar plots a local polynomial estimate of the semivariogram.

Usage

## S3 method for class 'fitsvar'
plot(
  x,
  y = NULL,
  legend = TRUE,
  xlab = "distance",
  ylab = "semivariance",
  xlim = NULL,
  ylim = c(0, 1.25 * max(x$fit$sv, na.rm = TRUE)),
  lwd = c(1, 2),
  add = FALSE,
  ...
)

## S3 method for class 'svar.bin'
plot(
  x,
  y = NULL,
  xlab = "distance",
  ylab = "semivariance",
  xlim = NULL,
  ylim = c(0, max(x$biny, na.rm = TRUE)),
  add = FALSE,
  ...
)

## S3 method for class 'np.svar'
plot(
  x,
  y = NULL,
  xlab = "distance",
  ylab = "semivariance",
  xlim = NULL,
  ylim = c(0, max(x$biny, na.rm = TRUE)),
  add = FALSE,
  ...
)

Arguments

x	a variogram object. Typically an output of functions np.svariso or fitsvar.sb.iso.
y	ignored argument.
legend	logical; if TRUE (default), a legend is added to the plot.
xlab	label for the x axis (defaults to "distance").
ylab	label for the y axis (defaults to "semivariance").
xlim	x-limits.
ylim	y-limits.
lwd	line widths for points (estimates) and lines (fitted model) respectively.
add	logical; if TRUE the semivariogram plot is just added to the existing plot.
...	additional graphical parameters (see par).

Value

No return value, called for side effects (generate the plot).
