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.
