Dear David, do you know how to get plotmath-like symbols in both rows? I tried s.th. like:
lab <- expression(paste(alpha==1, ", ", beta==2, sep="")) xlab <- substitute(expression( atop(lab==lab., bold(foo)) ), list(lab.=lab)) xyplot(0 ~ 0, xlab = xlab) Cheers, Marius On 2011-04-04, at 18:59 , David Winsemius wrote: > > On Apr 4, 2011, at 12:45 PM, Marius Hofert wrote: > >> Dear David, >> >> I intended to use another x-label.
