_D_e_s_c_r_i_p_t_i_o_n:

     This function generates plate IDs from the dimensions of the grid
     and spot matrices. Note that this function only applies to arrays
     with a regular plate layout, where the number of spots is a
     multiple of the number of wells on a plate (usually 96 or 384) and
     each well contributes  exactly one spot. It should thus be used
     with caution.

_U_s_a_g_e:

     maCompPlate(x, n=384)

_A_r_g_u_m_e_n_t_s:

       x: object of class '"marrayLayout"', '"marrayRaw"',
          '"marrayNorm"',  '"marraySpots"', or  '"marrayTwo"'.

       n: object of class "numeric", number of wells in each plate,
          usually 384 or 96.

_D_e_t_a_i_l_s:

     Having plate IDs may be useful for the purpose of normalization.
     Normalization by plate can be done using the function
     'maNormMain'.

_V_a_l_u_e:

     a vector of plate IDs ('factor').
