triangular {circular} | R Documentation

## 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

    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)
