Re: [R] Plotting 15 million points
Hi All I should have included this first up and I think I understand the problem. The load on the server I was running R was heavy which was causing everything to slow up. >summary(s) Min. 1st Qu.

Well, I only have 4.5 million rows (in a hundred plus variable dataframe) but the typical commands seem to work fine. hist() gave a plot almost instantly: hist(TRdta$ur_procreat, breaks=c(seq(0, 4, by=0.2), 20) ) Thanks, -Abhi __ 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.

Re: [R] Plotting 15 million points
Have you considered taking a random subset and plotting that? I'd bet you can get a really impression of the distribution with a few hundred thousand points at most.

[R] Plotting 15 million points
Hi All I have a vector of about 15 million numbers which I would like to plot. The goal is the see the distribution. I tired the usual steps. 1. Histogram : never gets complete my window freezes w/out log base 10 2. Density : I first calculated the kernel density and then plotted it which worked. It would be nice to superimpose histogram with density but as of now I am not able to get this data as a histogram. I tried ggplot2 which also hangs.
