plot(x, ..., split = FALSE, add_legend = TRUE, args_legend = list())
Arguments
x |
An |
... |
Additional arguments to pass the |
split |
A logical value indicating whether, for a directional semivariogram, the directional semivariograms should be displayed in a single or split panels. Default is FALSE, for a single panel. |
add_legend |
A logical value indicating whether a
legend should be included for a plot of directional
semivariograms when |
args_legend |

The arguments after ...
are only considered
if a directional semivariogram is provided, i.e.,
when x$ndir != 1

autosize
.
add_legend
and args_legend
