Re: [R] Compress (gzip) a pdf device - [ ] Message is from an unknown sender
By now It seems nobody have idea. zz - gzfile(C:/gzpdftest.gz, wb) pdf(file = zz) plot(USArrests) dev.off() close(zz) produce a file named 3 without any extension in my working directory. Also I don't have any news on how to gzip the pdf afterward (without using an external executable).

Re: [R] Compress (gzip) a pdf device - [ ] Message is from an unknown sender
I guess I don't understand what your're trying to do. gzip-ing a file from within R is easy enough: pdf(file=CompressMe.pdf) plot(rnorm(100)) dev.off() system(gzip CompressMe.pdf) I think you want something more complicated, but I'm not sure what. -Ista On Thu, Oct 1, 2009 at 6:41 AM, Daniele Amberti daniele.ambe...@ors.it wrote: By now It seems nobody have idea. zz - gzfile(C:/gzpdftest.gz, wb) pdf(file = zz) plot(USArrests) dev.off() close(zz) produce a file named 3 without any extension in my working directory.

Re: [R] Compress (gzip) a pdf device - [ ] Message is from an unknown sender
system() invokes the OS command specified by command, in the example you gave it means that gzip is installed and (assuming Windows OS) it is in your search path. I'd like to have a solution that do not use external programs.

Re: [R] Compress (gzip) a pdf device - [ ] Message is from an unknown sender
The latest version of the Rcompression package (www.omegahat.org/Rcompression) provides a gzip() function that does this. The example in the help page shows how. There is a source version of the package in the Omegahat repository (and on the package's Web site), but no binaries at this point. D.
