    function rtest_Wrap (r:numeric, Nr:integer, opt:integer)
    begin
      result = r ; variable-to-variable transfer of
                                  ; values and meta data
      result = rtest(r, Nr, opt) ; over write values with statistics
                                  ; meta data retained
      result@long_name = "cor. coef. sifnificance"
      if (isatt(result,"units")) then
          delete(result@units) ; no units
      end if
      
      return(result)
    end
