plot.variogram.cloud {gstat} | R Documentation |
Plot a sample variogram cloud, possibly with identification of individual point pairs
plot.variogram.cloud(x, identify = FALSE, digitize = FALSE, xlim, ylim, xlab, ylab, ...)
x |
object of class variogram.cloud |
identify |
logical; if TRUE, the plot allows identification of a series of individual point pairs that correspond to individual variogram cloud points (use left mouse button to select; right mouse button ends) |
digitize |
logical; if TRUE, select point pairs by digitizing a region with the mouse (left mouse button adds a point, right mouse button ends) |
xlim |
limits of x-axis |
ylim |
limits of y-axis |
xlab |
x axis label |
ylab |
y axis label |
... |
parameters that are passed through to plot.variogram (in case of identify = FALSE) or to plot (in case of identify = TRUE) |
if identify or digitize is TRUE,
a data frame of class point.pairs
with in its
rows the point pairs identified, if identify is F, a plot of the
variogram cloud (see plot.variogram)
