But you also might have the additional problem that too many data points just produce an incoherent solid blob, no matter the format.
Lots of folks have written about this. Check out JCGS and computer graphics literature for ideas. Also,this is one arena where fancy, dynamic, interactive software (maybe xgobi) might be useful. Maybe not (too much data). Finally, canonical answer: **appropriately** sample and plot only the sample data. The key is in defining "appropriately",of course. -- Bert Gunter Genentech -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Roger Peng Sent: Tuesday, April 15, 2008 2:34 PM To: Georg Ehret Cc: r-help Subject: Re: [R] heavy graphs It's probably best to choose a different format like PNG or jpeg. -roger On Tue, Apr 15, 2008 at 5:22 PM, Georg Ehret <[EMAIL PROTECTED]> wrote: > Dear R community, I am creating large graphs with hundreds of > thousands of datapoints.
