The plot you referred to depends on packages flowViz and flowCore from R-bioconductor. With lattice alone you can easily get all curves on the same level: densityplot(~ val | factor(id2), groups=factor(id1),data=a_df,pch='|')
But if that doesn't do it for you, you could write your own panel function. I don't have time to try it but I'm thinking one of these might work 1) create new ylim[1] from current.panel.limits()$ylim / number of groups dens<- density(x) use lines and polygons to draw the curves dens$x,dens$y at each new ylim level. 2) grid may come in handy here, splitting each panel into several viewports ? 3) use bwplot for "setup" but plot polygons of density (steps 2:3 from option 1) Good luck with that.
