Excellent reference. The only improvement I could think of is to abuse the non-standard evaluation of 'groups' to avoid repeating the name of the dataset, which would go something like xyplot(lifeExp ~ gdpPercap | factor(year), yDat, aspect = 2/3, grid = TRUE, scales = list(x = list(log = 10, equispaced.log = FALSE)), col = jDarkGray, pch = jPch, groups = list(cex = sqrt(pop/pi) / jCexDivisor, fill = color), panel = function(x, y, ..., groups, subscripts) { panel.xyplot(x, y, cex = groups$cex[subscripts], fill = groups$fill[subscripts], ...) }) Unfortunately, this doesn't work because prepanel.default.xyplot() tries to be too smart and assumes that 'groups' is a factor. A workaround is to override the default prepanel function; e.g., lattice.options(prepanel.default.xyplot = function(x, y, ...) list(xlim = extendrange(range(x)), ylim = extendrange(range(y)))) I will try to fix prepanel.default.xyplot() for the next update of lattice. -Deepayan > > On Mon, Mar 11, 2019 at 2:26 PM Sebastien Bihorel < > sebastien.biho...@cognigencorp.com> wrote: > > > Hi, > > > > I am a big user/fan of the lattice package for plotting.
