_D_e_s_c_r_i_p_t_i_o_n:

     Convert character to numerical spacing measure for within-array
     replicate spots.

_U_s_a_g_e:

     getSpacing(spacing, layout)

_A_r_g_u_m_e_n_t_s:

 spacing: character string or integer. Acceptable character strings are
          '"columns"', '"rows"', '"subarrays"' or '"topbottom"'.
          Integer values are simply passed through.

  layout: list containing printer layout information

_D_e_t_a_i_l_s:

     '"rows"' means that duplicate spots are printed side-by-side by
     rows. These will be recorded in consecutive rows in the data
     object.

     '"columns"' means that duplicate spots are printed side-by-sidy by
     columns. These will be separated in the data object by
     'layout$nspot.r' rows.

     '"subarrays"' means that a number of sub-arrays, with identical
     probes in the same arrangement, are printed on each array. The
     spacing therefore will be the size of a sub-array.

     '"topbottom"' is the same as '"subarrays"' when there are two
     sub-arrays.

_V_a_l_u_e:

     Integer giving spacing between replicate spots in the gene list.

_A_u_t_h_o_r(_s):

_S_e_e _A_l_s_o:

     An overview of LIMMA functions for reading data is given in
     03.ReadingData.

_E_x_a_m_p_l_e_s:

     getSpacing("columns",list(ngrid.r=2,ngrid.c=2,nspot.r=20,nspot.c=19))
     getSpacing("rows",list(ngrid.r=2,ngrid.c=2,nspot.r=20,nspot.c=19))
     getSpacing("topbottom",list(ngrid.r=2,ngrid.c=2,nspot.r=20,nspot.c=19))
