Dear List, There seems to be an bug in compactPDF() or at least an inconsistency with the documented behaviour. The documentations states: Details: This by default makes use of ?qpdf?, available from <URL: http://qpdf.sourceforge.net/>, including a Windows binary. If ?gs_cmd? is non-empty, GhostScript is used. I don't...

I am failing to get compactPDF to make any change to a pdf file that, a/c to the message from the CRAN upload site, can be very substantially compacted. Any ideas what may be wrong? I have also tried recreating the pdf file. I also tried R CMD build --resave-data --compact-vignettes DAAG The data files compact alright (but I...

I am using tools::compactPDF for reducing the size of some pdf-files with GhostScript. I had some trouble in the beginning as the documentation seems not to match the usage of the function. For GhostScript, one has to set the argument gs_cmd, which has the following description: gs_cmd - Character string giving the path to...

...the same warning and [2] where a number of possible ways to corrupt PDF (and warning messages from various software) is investigated, including this one. Ironically, this is almost in scope for R-package-devel, because the message comes from "qpdf", a tool used by R CMD check (and tools::compactPDF() in particular). The internal "table of contents" at the end of the PDF file contains nonsensical references, which "qpdf" complains about. If you run the following command line: qpdf "/path/to/original/file.pdf" "/path/to/reconstructed/file.pdf" ...qpdf w...

...plastic1.pdf' Execution halted * checking PDF version of manual ... OK I am unable to determine why the file fig/plot-plastic1.pdf cannot be opened. It is in my inst/doc/fig directory & is regenerated by the .Rnw file. What could cause this? Second, I have tried manually running tools::compactPDF("HE-examples.pdf) on the .pdf file under inst/doc in the package, but no change is made to the .pdf file. I can't see any way to correct this. -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. York University Voice: 416 736-5115 x66249 Fax: 416 736...

Buenas tardes a todos, Estoy interesado en realizar varios gráficos y luego guardarlos individualmente como PDF. Hasta ahí todo bien. Sin embargo, el archivo resultante tiene aproximadamente 20MB. Podría alguien por favor indicarme cómo reducir su tamaño? A continuación un ejemplo de lo que intento hacer y mi sessionInfo(). Estoy usando Mac OS X. Muchas gracias, Jorge Ivan Velez # R code

This is supported on most but not all R platforms. o Function compactPDF() in package tools now takes the default for argument gs_quality from environment variable GS_QUALITY: there is a new value "none", the ultimate default, which prevents GhostScript being used in preference to qpdf just because environment variable R_GSCMD is set....

Package tools has a new function compactPDF() to try to reduce the size of PDF files _via_ qpdf or gs. ? tar() has a new argument extra_flags. ? dotchart() accepts more general objects x such as 1D tables which can be coerced by as.numeric() to a numeric vector, with a warning since that might not be appropriate....
