_D_e_s_c_r_i_p_t_i_o_n:

     Read in a series of array image analysis output files as data
     frames.

_U_s_a_g_e:

     read.series(slides, path=NULL, suffix="spot", ...)

_A_r_g_u_m_e_n_t_s:

  slides: character vector giving the names of files to be read in. Any
          suffix such as ".spot" or ".gpr" which is common to all the
          files can be omitted.

    path: character string giving the directory containing the files.
          Can be omitted if the files are in the current working
          directory.

  suffix: character string giving a suffix such as "spot" or "gpr" to
          be added to each file. If 'NULL' then no suffix is added.

     ...: any other arguments to be passed to 'read.table'

_D_e_t_a_i_l_s:

     This function performs a series of calls to 'read.table'. The
     image analysis output files are assumed to have been edited to
     remove all pre-heading material. The files are assumed to contain
     only column names and data. In most cases only can use
     'read.maimages' instead.

     The data.frames produced by this command will typically be
     processed further using one of the functions 'rg.spot',
     'rg.genepix' or 'rg.quantarray'.

_V_a_l_u_e:

     No value is returned. However a series of data.frames are created
     on the current environment with names of the form filename.suffix.
     The files names are given by the elements of 'slides' and the
     suffix is given by 'suffix'.

_S_e_e _A_l_s_o:
