## bug in y limits in bwplot

tmp <- data.frame(y=1:10, a=factor(rep(1:2,5)))

## x limits in bwplot works as expected
bwplot(y ~ a, data=tmp, horizontal=F)  # works

bwplot(y ~ a, data=tmp, horizontal=F,  # works
       xlim=c(-1,5))

bwplot(y ~ a, data=tmp, horizontal=F,  # works
       scales=list(x=list(limits=c(-1,5))))


## problem with y limits in bwplot
bwplot(a ~ y, data=tmp, horizontal=T)  # works

bwplot(a ~ y, data=tmp, horizontal=T,  # works
       ylim=c(-1,5))

bwplot(a ~ y, data=tmp, horizontal=T,  # error message
       scales=list(y=list(limits=c(-1,5))))

This turns out to be a long-standing bug (in all the lattice functions in 
fact, not only bwplot). Should be fixed in the next release. A workaround is 
to use xlim and ylim directly instead of limits in scale.
