It is not clear whether this is an asynchronous process that uses new data to draw some of the plots but not others. > The plots are slowly redrawn from the upper left corner of the quartz window > to the bottom right. > > > That makes me wonder; > Is there a way to buffer the graphical device before updating it? > Or are there any other solutions for R that enables to smoothly plot / > visualize data in 'real-time'? You can split 'screens' on a graphics device to which you can send plotting output. You already know that you can construct 'layout's. You can have multiple interactive output devices. The split-screen method is incompatible with layout. ?Devices ?dev.cur ?screen -- David Winsemius Alameda, CA, USA ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
