Have you tried the 'sm.density' function from the sm library? I used it for a dataset which 'only' had 13 points. I'm new to R and am trying to perform a simple, yet problematic task. I have two variables for which I would like to measure the correlation and plot versus each other. Howeve

You might want to try hexbin (hexagonal binning) in the BioConductor suite (see www.bioconductor.org). HTH, Andy > From: Obi Griffith > > I'm new to R and am trying to perform a simple, yet > problematic task. I > have two variables for which I would like to measure the > correlation and >

[R] density plot for very large dataset

I'm new to R and am trying to perform a simple, yet problematic task. I have two variables for which I would like to measure the correlation and plot versus each other. However, I have ~30 million data points measurements of each variable. I can read this into R from file and produce a plot
