   location,scale: location and scale parameters.

        These functions provide information about the Cauchy
        distribution with location parameter `location' and
        scale parameter `scale'.

        `dcauchy', `pcauchy', and `qcauchy' are respectively
        the density, distribution function and quantile func-
        tion of the Cauchy distribution.  `rcauchy' generates
        random deviates from the Cauchy.

        If `location' or `scale' are not specified, they assume
        the default values of `0' and `1' respectively.

        The Cauchy distribution with location l and scale s has
        density

                  f(x) = 1 / (pi s (1 + ((x-l)/s)^2))

        for all x.

        `dt' for the t distribution which generalizes
        `dcauchy(*, l = 0, s = 1)'.
