Source: R/fabric_plots.R
vollmer_plot.Rd

Creates a fabric plot using the eigenvalue method

Usage

vollmer_plot(x, labels = NULL, add = FALSE, ngrid = c(5, 5, 5), ...)

Arguments

x

object of class "Vec3", "Line", or "Plane".

labels

character. text labels

add

logical. Should data be plotted to an existing plot?

ngrid

integer or 3-element vector specifying the amount of gridlines for the P, G, and G axes. Constant grid spacing when only one integer is given. NULL when no grid.

...

optional graphical parameters

Value

plot and when stored as an object, the P, G, and R values as a numeric vector.
