dtri

Triangular Density Function

Returns the triangular density function evaluated at a particular value.

dtri(theta, r)

`theta`	vector of angles measured in radians at which to evaluate the density function.
`r`	concentration parameter of the distribution. r must be between 0 and 4/pi^2.

Returns the triangular density function evaluated at theta.
