_D_e_s_c_r_i_p_t_i_o_n:

     Density, distribution function and random generation for the von
     Mises circular distribution.

_U_s_a_g_e:

     dvonmises(x, mu, kappa)
     pvonmises(q, mu, kappa, tol = 1e-20)
     rvonmises(n, mu, kappa, units = c("radians", "degrees"), ...)

_A_r_g_u_m_e_n_t_s:

    x, q: a vector. The object is coerced to class 'circular'.

       n: number of observations.

      mu: mean direction of the distribution.

   kappa: non-negative numeric value for the concentration parameter of
          the distribution.

   units: units of measure desired.

     tol: the precision in evaluating the distributon function.

     ...: parameters passed to 'circular'.

_V_a_l_u_e:

     'dvonmises' gives the density, 'pvonmises' gives the distribution
     function and 'rvonmises' generates random deviates.

_A_u_t_h_o_r(_s):
