     ...: graphical arguments

      at: numeric in [0,1]: Which portions/proportions should be
          marked?

      by: numeric in (0,1]:Steps between protions/proportions

   parts: numeric vector subset of {1,2,3}: the variables to be marked

   total: The total amount to be used in labeling

    labs: logical: plot the labels?

   lines: logical: plot the lines?

    unit: marking the units e.g. "%"

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

     Isoportion lines give lines of the same portion of one of the
     parts, while isoproportion line gives lines of the same ratio
     between two parts. The isoproportion lines are Aitchison-lines in
     the simplex, while the isoportion-lines are, up to my knowledge,
     not.

_N_o_t_e:

     Currently IsoLines only work individual plots. This is mainly due
     to the fact that I have no idea, what the user interface of this
     function should look like for multipanel plots. This includes
     philosophical problems with the meaning of isoportions in case of
     marginal plots.
