_D_e_s_c_r_i_p_t_i_o_n:

     This class provides the link to the 'ROOT' scheme file and  the
     'ROOT' trees contained therein. It extends class 'TreeSet'.

     Objects can be created using the functions 'import.expr.scheme',
     'import.exon.scheme', 'import.genome.scheme' or 'root.scheme'.

_S_l_o_t_s:


     '_c_h_i_p_n_a_m_e': Object of class '"character"' representing the
          Affymetrix chip name.

     '_c_h_i_p_t_y_p_e': Object of class '"character"' representing the chip
          tpye,  either GeneChip, GenomeChip or ExonChip.

     '_p_r_o_b_e_i_n_f_o': Object of class '"list"' representing chip
          information,  including nrows, ncols, number of probes, etc.

     '_m_a_s_k': Object of class '"data.frame"'. The data.frame can contain
          the mask  used to identify the probes as e.g. PM, MM or
          control probes.

     '_s_e_t_n_a_m_e': Object of class '"character"' representing the name to
          the 'ROOT' file subdirectoy where the 'ROOT' scheme trees are
          stored; it is identical to 'chipname'.

     '_s_e_t_t_y_p_e': Object of class '"character"' describing the type of
          treeset stored in 'setname', i.e. scheme.

     '_r_o_o_t_f_i_l_e': Object of class '"character"' representing the name 
          of the 'ROOT' scheme file, including full path.

     '_f_i_l_e_d_i_r': Object of class '"character"' describing the full path
          to the system directory where 'rootfile' is stored.

     '_n_u_m_t_r_e_e_s': Object of class '"numeric"' representing the number of
           'ROOT' trees stored in subdirectoy 'setname'.

     '_t_r_e_e_n_a_m_e_s': Object of class '"list"' representing the names of
          the  'ROOT' trees stored in subdirectoy 'setname'.

_E_x_t_e_n_d_s:

     Class '"TreeSet"', directly.

_M_e_t_h_o_d_s:


     _a_t_t_a_c_h_M_a_s_k 'signature(object = "SchemeTreeSet")': exports scheme
          tree from  'ROOT' scheme file and and saves as data.frame
          'mask'.

     _c_h_i_p_M_a_s_k 'signature(object = "SchemeTreeSet")': extracts
          data.frame 'mask'.

     _c_h_i_p_M_a_s_k<- 'signature(object = "SchemeTreeSet", value =
          "data.frame")': replaces  data.frame 'mask'.

     _c_h_i_p_N_a_m_e 'signature(object = "SchemeTreeSet")': extracts slot
          'chipname'.

     _c_h_i_p_T_y_p_e 'signature(object = "SchemeTreeSet")': extracts slot
          'chiptype'.

     _c_h_i_p_T_y_p_e<- 'signature(object = "SchemeTreeSet", value =
          "character")': replaces  slot 'chiptype'.

     _e_x_p_o_r_t 'signature(object = "SchemeTreeSet")': exports 'ROOT' trees
           as text file, see 'export-methods'.

     _n_c_o_l_s 'signature(object = "SchemeTreeSet")': extracts the physical
          number of  array columns from slot 'probeinfo'.

     _n_r_o_w_s 'signature(object = "SchemeTreeSet")': extracts the physical
          number of  array rows from slot 'probeinfo'.

     _p_r_o_b_e_I_n_f_o 'signature(object = "SchemeTreeSet")': extracts slot
          'probeinfo'.

     _r_e_m_o_v_e_M_a_s_k 'signature(object = "SchemeTreeSet")': replaces
          data.frame 'mask'  with an empty data.frame of dim(0,0).
