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

     The '"CsparseMatrix"' class is the virtual class of all sparse
     matrices coded in sorted compressed column-oriented form. Since it
     is a virtual class, no objects may be created from it.  See
     'showClass("CsparseMatrix")' for its subclasses.

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

     '_i': Object of class '"integer"' of length nnzero (number of
          non-zero elements).  These are the row numbers for each
          non-zero element in the matrix.

     '_p': Object of class '"integer"' of pointers, one for each column,
          to the initial (zero-based) index of elements in the column.

     '_f_a_c_t_o_r_s', '_D_i_m', '_D_i_m_n_a_m_e_s': inherited from the superclass, see
          the 'sparseMatrix' class.

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

     Class '"sparseMatrix"', directly. Class '"Matrix"', by class
     '"sparseMatrix"'.

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

     _c_r_o_s_s_p_r_o_d 'signature(x = "CsparseMatrix", y = "missing")': ...

_S_e_e _A_l_s_o:

     its superclass, 'sparseMatrix', and, e.g., class 'dgCMatrix' for
     the links to other classes.
