plot.rtopVariogramCloud function

Plot and Identify Data Pairs on Sample Variogram Cloud

Plot a sample variogram cloud, possibly with identification of individual point pairs

## S3 method for class 'rtopVariogramCloud'
plot(x, ...)

Arguments

• x: object of class variogramCloud

• ...: parameters that are passed through to plot.variogramCloud

  The most important are:

  • 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
  • keep: logical; if TRUE and identify is TRUE, the labels identified and their position are kept and glued to object x, which is returned. Subsequent calls to plot this object will now have the labels shown, e.g. to plot to hardcopy

Note

This function is mainly a wrapper around plot.variogramCloud, necessary because of different column names and different class names. The description of arguments and value can therefore be found in the help page of plot.variogramCloud.

Examples

rpath = system.file("extdata",package="rtop")
library(sf)
observations = st_read(rpath, "observations")

observations$obs = observations$QSUMMER_OB/observations$AREASQKM

# Create the sample variogram
rtopVario = rtopVariogram(observations, params = list(cloud = TRUE))
plot(rtopVario)
