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

     Very simple wrapper function that draws a boxplot, histogram and
     hierarchical tree of expression  data

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

     overview(dataset, label=NULL, title="", ...)

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

 dataset: a 'matrix', 'data.frame',  'exprSet' or 'marrayRaw'.   If the
          input is gene expression data in a 'matrix' or 'data.frame'.
          The  rows and columns are expected to contain the variables
          (genes) and cases (array samples)  respectively.

   label: Vector, labels to be placed on samples in plots. Default is
          rownames(dataset)

   title: Character, label to be placed on plots. Default is NULL

     ...: further arguments passed to or from other methods 

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

     The hierarchical plot is produced using average linkage cluster
     analysis with Eisen's  correlation metric.

_S_e_e _A_l_s_o:

     See also as 'boxplot', 'hclust',  'hist'
