     'maStat' calculates various statistcs for genes in the array
     `expr' using the functions in `funNames'.It returns an matrix of
     values.

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

     maStat(expr, funNames, ...)

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

    expr: An object of class "matrix", "dataframe", "marrayRaw",
          "marrayNorm" or "exprSet" that contains gene expression data.

funNames: Either a character strings containning the names of functions
          or a list of statistics functions.

     ...: further arguments to the functions is 'funNames'

     .

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

     A matrix of values.
