[R] Lattice - parallel: xlim and adding lines

[T.A.Wassenaar]

Hi Sundar,

Thanks for the reply. And, oops, the panel.parallel.new 
shouldn't be in there. That is a revised panel function to 
color according to a group. As with strange, that would 
generally be 'not-expected', i.e., in the present case, 
not having an x-axis running from -1 to 1 for all ranges. 
I would at least expect to have zero in the middle, but 
that is not so. Excuse me for not expanding 'strange' 
previously. I have read the guide.., some while ago.

Thanks again,

Tsjerk
