is there a way to reduce the size of pdf files in R: ? compression? lower dpi ? or some other option?
It would help if we knew how big your pdf is and why it is big. Can you show an example or at least describe the process used to generate the file and what you goals are in creating/displaying the file? -- Gregory (Greg) L.

Using a large resolution gives very good results, certainly publication quality. cheers, Paul
The file is a large number of scatterplot matrices (120pp of 4x4 matrix) the individual plots may have up to several hudred points. I am already using the "useDingbats" but the files are still very large - I can reduce them about 50% in cute.pdf by changing the dpi setting but it would be good to handle directly in R They need to be screen/ draft print quality only not for publication.

Dear Nevil,
Converting your pdf to png will be the most efficient way to reduce the
file size with scatter plots.
You can either export directly to pdf or first create a pdf and then use
ghostscript to convert it into png. I tend to the the latter because it
is easier to get plots with a consistent layout. The convertion can be
done within R. See the code below.
system("C:/Progra~1/gs/gs8.64/bin/gswin32 -r300 -dSAFER -dBATCH
-dNOPAUSE -sDEVICE=png16m -dGraphicsAlphaBits=4
-sOutputFile=fig_Power_Resid.png fig_Power_Resid.pdf")
HTH,
Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

or possibly use smoothScatter() to produce the scatter plots....
