_D_e_s_c_r_i_p_t_i_o_n:

     ControlCode is a matrix representing certain regular expression
     pattern and the control status of the spotted probe sequences.
     This function uses `grep' searches for matches to `pattern' (its
     first argument) within the character vector `x' (second argument).

_U_s_a_g_e:

     maGenControls(Gnames, controlcode, id = "ID")

_A_r_g_u_m_e_n_t_s:

  Gnames: An object of class 'matrix', 'data.frame' or 'marrayInfo'
          which contains  description of spotted probe sequences.

controlcode: A character matrix of n by 2 columns. The first column
          contains a few regular expression of spotted probe sequences
          and the second column contains the corresponding control
          status.

      id: the column number of column name in 'Gnames' that contains
          description of each spot on the array.

_V_a_l_u_e:

     A vector of characters recording the control status of the spotted
     probe sequences.
