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

     'rmaov' performs the classical balanced split-plot ANOVA, with
     'summary' providing the table. This is the so-called repeated
     measures ANOVA.

     For unbalanced data, 'elliptic' will perform the analysis for one
     or two levels of nesting.

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

     rmaov(response, tvcov=NULL, ccov=NULL, analysis=TRUE)

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

response: A matrix or dataframe of response values with units as rows
          and repeated measures as columns.

   tvcov: A numeric vector or factor variable defining the clusters. If
          there are several levels of nesting, a matrix or dataframe
          with columns of such variables defining the nested clusters
          starting with the highest level (that is, from slowest to
          fastest varying). If not provided, each response value of a
          unit is assumed to belong to a different cluster (that is,
          one factor with 'ncol(response)' levels is assumed).

    ccov: A vector or factor variable for one inter-subject covariate
          or a matrix, dataframe, or list of several such variables.

analysis: If FALSE, the design matrix is set up, but the analysis is
          not performed.

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

     The fitted model is returned.
