[R] single strip for the same group in dotplot lattice

[Luigi Marongiu]

Dear Philip,
the data is indeed a toy data: the real one will have 15 panels (=targets)
and two or three clusters. this means that I will have 15 strips with the
label "run 1" = "cluster 1" etc. the point of the toy data is that I get a
4x4 panel plot with 8 strips labelled "run 1", "run 2", "A" and "B". What I
am looking for is to collapse the strips so to get only one label "run 1"
and only one with "run 2" in order to simplify the plot. Hope this helps.
Thanks
Luigi
