circular (version 0.4-93)

triangular: Triangular Density Function

Description

Density and random generation for the Triangular circular distribution.

Usage

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

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

the attribute of the resulting object.

Value

dtriangular gives the density and rtriangular generates random deviates.

Examples

# NOT RUN {
data1 <- rtriangular(100, 0.3, control.circular=list(units="degrees"))
plot(data1)

ff <- function(x) dtriangular(x, rho=0.3)
curve.circular(ff, shrink=1.2, join=TRUE)
