Description

Density and random generation for the Triangular circular distribution.

Usage

dtriangular(x, rho)
rtriangular(n, rho, control.circular=list())

Value

dtriangular gives the density and rtriangular generates random deviates.

Arguments

x

a vector. The object is coerced to class circular.

n

number of observations.

rho

concentration parameter of the distribution. rho must be between 0 and \(4/pi^2\).

control.circular
