You can try the combination of c.trellis and update from the latticeExtra package. For example:
p <- xyplot(1~1)
update(c(p, p, p, p), xlab='SomeText', ylab='MoreText')
update(c(p, p, p, p), xlab=c('SomeText', 'SomeText2'), ylab=c('MoreText', 'MoreText2'))
There are lots of examples in help(c.trellis).
