The best way is to try it and see if you like it. I have used it on
plots with 150,000 point and it provided a good picture of what was
going on.

I thought running it through latex will compress the pdf - but this

I personally prefer the pdftk approach* over the ghostscript
option** as the latter seems to give me a number of problems on
Windows XP.
*if you install pdftk (and put it in your search path), after you
create filename.pdf with pdf(), do
pdftk filename.pdf cat output newfilename.pdf compress
or
pdftk filename.pdf cat output newfilename.pdf compress dont_ask
**if you have ghostview installed (and in your search path),
bitmap("filename.pdf",type="pdfwrite")
plot(...)
dev.off()

Subject: Re: [R] Pdf file size for very scatter plots
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

Have you tried using pch='.'?
Also you might consider using 'hexbin' for creating the scatter plot.

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. I'd
rather stick with pdf or ps as I am using latex.
thanks,
Nazareno
