Re: [R] PDF Compression
There was a previous post about this also:
http://tolstoy.newcastle.edu.au/R/e2/help/07/05/17475.html
I was able to use bitmap(,type="pdfwrite") on Ubuntu Linux but had trouble
getting it to work on Windows.
For now, it's kind of kludgey but I have in my .Rprofle (or .Rprofile.site on
Windows):
compressPDF <- function(x) {
system(paste("pdftk",x,"output",sub("\\.pdf","c.pdf",x),
"compress dont_ask"))
unlink(x)
}
so after I plot something I would call compressPDF() on the same pdf file
pdf("plot.pdf"); plot(1:10); dev.off()
compressPDF("plot.pdf")
which renames it from 'plot.pdf' to 'plotc.pdf' to remind myself that I already
compressed it...

In general png can be larger than pdf but other disadvantages are more important. When I have created curves in R that are composed of thousands of data points, the compression of pdf I've achieved with pdftk has been amazing.

Re: [R] PDF Compression
Gabor, Interesting. I have had success compressing the pdf generated by R with pdftk. However when I incorporate that in a pdflatex document it ends up decompressed in the final pdf.

Re: [R] PDF Compression
Hi, You could have a look at exporting the pdfs using the Cairo package. cheers, Paul David Keegan schreef: Hi, I am generating a large number of graphs with pdf() and incorporating them in pdf document using pdflatex. According to the pdf() help: 'pdf' writes uncompressed PDF. It is primarily intended for producing PDF graphics for inclusion in other documents, and PDF-includers such as 'pdftex' are usually able to handle .compression. But pdflatex incorporates the R graphs without compressing them. They appear in the final document in cleartext, almost but not identical to what was generated by R. I tried the latex settings "\\pdfcompresslevel=9", "\\pdfobjcompresslevel=3". They reduced the overall size of the final document slightly, but didn't cause the embedded R graphs to be compressed. Can anyone suggest how I can get pdflatex to compress the R graphs while embedding them? My output files are very big, and I know they would be substantially smaller if the R graphs were compressed.
