I had imagined that the factor level character strings could be automagically
separated by substituting '\n' at each space or dash or wahtever:
strip.new <- function( which.given, which.panel, factor.levels, ...){
panel.text( x=0.5,y=1.5, lab=gsub("\\ ", "\n", factor.levels)
)}
# Need to tweak the line height
xyplot(y~x|f, strip=strip.new)
Your approach of changing the levels to be pre-split with '\n's may be more
straightforward.
