When I first started using an early port of S, the main way to create graphs was with the "printer" graphics device which created plots like this (back then that was impressive). S-PLUS does still have the printer graphics device to do things like this, but I don't think that anyone has ever implemented it for R (those with the skill don't have the desire). It has been discussed a couple of times in the past on this list, but I don't think it ever went very far.
The program gnuplot has support for a dumb terminal type of plotting that also creates this type of plot. There is a very crude interface between R and gnuplot in the TeachingDemos package (see ?gp.open). One approach would be to have R create the appropriate data (binning, quartiles, ...) and send that to gnuplot for plotting as text (this would require a separate download and install of gnuplot). -- Gregory (Greg) L.
