Density, and random generation for the wrapped Cauchy circular distribution.

1 2	dwrappedcauchy(x, mu = circular(0), rho = exp(-1)) rwrappedcauchy(n, mu = circular(0), rho = exp(-1), control.circular=list())

`x`	a vector. The object is coerced to class `circular`.
`n`	number of observations.
`mu`	mean direction of the distribution as a `circular` object.
`rho`	concentration parameter of the distribution. `rho` must be in the interval from 0 to 1.
`control.circular`	the attribute of the resulting object.

dwrappedcauchy gives the density and rwrappedcauchy generates random deviates.
