[R] lattice multiple y-scale possible?

[Dennis Murphy]

Hi:

bwplot(dat~site|parameter,data=mydat,
     layout=c(1,5),
     cex=2,
     xlab="Site Name",
     ylab="",
     labels=levels(mydat$site),
     scales=list(tick.number=list(4), rot = c(0, 90),
                 y = list(relation = 'free')))

Does that work?
