     randtest is a generic function. It proposes methods for the
     following objects 'between', 'discrimin', 'coinertia' '...'

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

         randtest(xtest, ...)
         plot.randtest(x, nclass = 10, coeff = 1, ...)
         as.randtest (sim, obs, call = match.call())
         print.randtest (x, ...)

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

   xtest: an object used to select a method

       x: an object of class 'randtest'

     ...: '...' further arguments passed to or from other methods; in
          'plot.randtest' to 'hist'

  nclass: a number of intervals for the histogram

   coeff: to fit the magnitude of the graph

     sim: a numeric vector of simulated values

     obs: a numeric vector of an observed value

    call: a call order

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

     'as.randtest' returns a list of class 'randtest'
      'plot.randtest' draws the simulated values histograms and the
     position of the observed value
