Fabric Plot of Woodcock (1977)

Source: R/fabric_plots.R
woodcock_plot.Rd

Creates a fabric plot using the eigenvalue method

Usage

woodcock_plot(
  x,
  labels = NULL,
  add = FALSE,
  max = 7,
  main = "Woodcock diagram",
  ...
)

Arguments

x

either an object of class "Vec3", "Line", "Ray", "Plane", "Pair", or "Fault" where the rows are the observations and the columns are the coordinates, or an "ortensor" object.

labels

character. text labels

add

logical. Should data be plotted to an existing plot?

max

numeric. Maximum value for x and y axes. If NULL, it is calculated from the data.

main

character. The main title for the plot.

...

optional graphical parameters

Value

A plot and when stored as an object, the orientation tensor's eigenvalues and eigenvectors as a list.
