vonMises: von Mises Density Function

Description

Density, distribution function and random generation for the von Mises circular distribution.

Usage

dvonmises(x, mu, kappa)
pvonmises(q, mu, kappa, tol = 1e-20)
rvonmises(n, mu, kappa, units = c("radians", "degrees"), ...)

Arguments

x, q
a vector. The object is coerced to class circular.
n
number of observations.
mu
mean direction of the distribution.
kappa
non-negative numeric value for the concentration parameter of the distribution.
units
units of measure desired.
tol
the precision in evaluating the distributon function.
...
parameters passed to circular.

Value

  • dvonmises gives the density, pvonmises gives the distribution function and rvonmises generates random deviates.
