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

     The 'brain' data frame has 90 rows and 2 columns. It contains
     pairs of observations (var) and factor levels (class).

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

     data(brain)

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _c_l_a_s_s - factor with levels 'c' = control-group, 'l' = left
          hemisphere brain-damage,  'r' = right hemisphere brain-damage

     _v_a_r - score for the reaction

_D_e_t_a_i_l_s:

     The effects of uniliteral left hemisphere (LH) and right
     hemisphere (RH) lesions on the accuracy of choice and speed of
     response in a four-choice reaction time task were examined by
     Tartaglione et al. (1191). The subjects consisted of 30 controls,
     30 LH and 30 RH brain-damaged patients, so this is an example for
     a balanced one-factorial design.

_R_e_f_e_r_e_n_c_e_s:

     "A unified approach to Simultaneous Rank Test Procedures in the
     Unbalanced One-way Layout" written by Ullrich Munzel and Ludwig
     Hothorn.

_E_x_a_m_p_l_e_s:
