[R] after setting auto.key=TRUE, legend become inconsistent with the graph

[Gabor Grothendieck]

Set the various plotting parameters in par.settings= in which
case both the legend and the plot itself will be taken from there.
See for example:

where superpose.line parameters are set.  Similarly you can
set superpose.symbol parameters.
