Citing myself, on 8 Feb 2002 I wrote in "[Rd] interaction.plot (with
misplaced legend) (PR#1305)":

"[...] for the x-axis annotation mtext() is used. I'd suggest to change
line 35:
  mtext(xlabs, 1, at = xvals) # old
to
  axis(1, at = xvals, labels = xlabs, ...) # new"

This would solve a couple of inconsistencies in interaction.plot().
