     Objects can be created using the 'simpleViewer' function.

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


     '_d_e_v': Object of class '"ViewerDevice"', typically the result of a
          call to 'viewerDeviceVp'.

     '_s_t_a_t_e': Object of class '"ViewerState"', typically the result of
          a call to 'viewerState'.

     '_d_a_t_a': Object of class '"ViewerData"', typically the result of a
          call to the function 'viewerData' or 'viewerDataFrame'.

     '_s_t_a_r_t_c_o_l': Object of class '"numeric"' giving the first column in
          the current view.

     '_s_t_a_r_t_r_o_w': Object of class '"numeric"' giving the first row in
          the current view. 

     '_t_h_r_e_s_h_o_l_d': Object of class '"numeric"' giving the threshold
          below which lines are drawn rather than text.

     _d_r_a_w 'signature(v = "ViewerSimple")': render the current view of
          the data.

     _l_r_e_n_d 'signature(v = "ViewerSimple")': navigate to the last
          column.

     _l_r_g_r_o_w 'signature(v = "ViewerSimple")': zoom in the view to
          exclude the left/rightmost column.

     _l_r_h_o_m_e 'signature(v = "ViewerSimple")': navigate to the first
          column. 

     _l_r_s_c_r_o_l_l 'signature(v = "ViewerSimple")': navigate to the
          next/previous column. 

     _l_r_s_h_r_i_n_k 'signature(v = "ViewerSimple")': zoom out the view to
          include the next/previous column.

     _u_d_e_n_d 'signature(v = "ViewerSimple")': navigate to the last row.

     _u_d_g_r_o_w 'signature(v = "ViewerSimple")': zoom in the view to
          exclude first/last row.

     _u_d_h_o_m_e 'signature(v = "ViewerSimple")': navigate to the first row.

     _u_d_s_c_r_o_l_l 'signature(v = "ViewerSimple")': navigate to the
          next/previous row.

     _u_d_s_h_r_i_n_k 'signature(v = "ViewerSimple")': zoom out the view to
