     Match values in index

_U_s_a_g_e:

     match(x, table, nomatch = NA, incomparables = FALSE)
      x %in% table

_A_r_g_u_m_e_n_t_s:

       x: a set of search values

incomparables: not yet used 

_D_e_t_a_i_l_s:


       'match'  redefined version of 'match' automatically recognizing index tables
        '%in%'  redefined version of '%in%' (redefinition needed for finding redefined 'match' in spite of namespaces)

_V_a_l_u_e:

     Function 'match' returns a vector of original positions (or the
     nomatch value NA), function '%in%' returns a logical vector.
