Speed up plot() function for large dataset

Question

I am using plot() for over 1 mln data points and it turns out to be very slow.

Is there any way to improve the speed including programming and hardware

Answer 1

have you looked at the tabplot package. it is designed specifically for large data http://cran.r-project.org/web/packages/tabplot/ I use that its faster than using hexbin (or even the default sunflower plots for overplotting)

also i think Hadley wrote something on DS 's blog modifying ggplot for big data at http://blog.revolutionanalytics.com/2011/10/ggplot2-for-big-data.html

"""I'm currently with working another student, Yue Hu, to turn our research into a robust R package.""" October 21, 2011

Maybe we can ask Hadley if the updated ggplot3 is ready
