Mac or Windows...?
Once (in the original implementation of the device) it was possible to set "antialias=FALSE" when opening quartz() to get reasonable speed in drawing, but of course you loose the nice quartz antialias effect, and get results similar to X11 or windows device. it seems that this option has no longer effect > quartz() > system.time(example(heatmap)) [1] 2.587 0.180 4.460 0.000 0.000 > quartz(antialias=FALSE) > system.time(example(heatmap)) [1] 2.573 0.176 4.545 0.000 0.000 > x11() > system.time(example(heatmap)) [1] 1.967 0.145 3.741 0.000 0.000 Simon, have you time to check? stefano

I agree with most of what he said here. I would note however that we routinely have to use the X11() device instead of quartz() device in R due to speed issues. I have code that would take several minutes drawing a heatmap using quartz device. One day I accidentally started X11 device instead and found the same code executed in about fifteen seconds. ---------------------------------------------------------- SIGSIG -- signature too long (core dumped)
