vm_qqplot: von Mises Quantile-Quantile Plot

In tectonicr: Analyzing the Orientation of Maximum Horizontal Stress

von Mises Quantile-Quantile Plot

Description

Produces a Q-Q plot of the data against a specified von Mises distribution to graphically assess the goodness of fit of the model.

Usage

vm_qqplot(
  x,
  w = NULL,
  axial = TRUE,
  mean = NULL,
  kappa = NULL,
  xlab = "von Mises quantile function",
  ylab = "Empirical quantile function",
  main = "von Mises Q-Q Plot",
  ...
)

Arguments

x	numeric. Angles in degrees
w	numeric. optional weightings for x to estimate mean and kappa.
axial	Logical. Whether data are uniaxial (axial=FALSE)
mean	numeric. Circular mean of the von Mises distribution. If NULL, it will be estimated from x.
kappa	numeric. Concentration parameter of the von Mises distribution. If NULL, it will be estimated from x.
xlab, ylab, main	plot labels.
...	graphical parameters

Value

plot

Examples

x_vm <- rvm(100, mean = 0, kappa = 4)
vm_qqplot(x_vm, axial = FALSE, pch = 20)

x_unif <- runif(100, 0, 360)
vm_qqplot(x_unif, axial = FALSE, pch = 20)
