Jim, Thanks for the answer. Using pch="." reduces the file to ~3MB... Still large.
I'll look into hexbins, but if I understand it right, it would 'round' points which are nearby into a same hexagon, right? Couldn't that result in an inaccurate view of a scatter plot? Here's the code I'm using: pdf(); plot(rnorm(1e5), rnorm(1e5), pch = "."); dev.off() thanks again, Nazareno On Fri, Aug 15, 2008 at 12:27 PM, jim holtman <[EMAIL PROTECTED]> wrote: > Have you tried using pch='.'? > > Also you might consider using 'hexbin' for creating the scatter plot. > > On Fri, Aug 15, 2008 at 12:24 PM, Nazareno Andrade > <[EMAIL PROTECTED]> wrote: >> Dear all, >> >> I am plotting a scatter plot for a large sample (1e+05 ordered pairs). >> This produces a large (~5MB) file in a pdf or postscript terminal, and >> I am wondering whether there are methods for reducing the size of the >> resulting file so that it is easier to include it in a document.
