Take a look at tools::compactPDF - you need to have either qpdf or ghostscript installed, but it can make a huge difference to pdf file size.

17 Jun 2010 Obviously I don't need all the detail (every pixel of the raster) represented in the pdf and would rather have it reduced in size somehow. So I wrote an R function to automate the following: take an existing pdf and run ps2pdf on it as an intial compression step. Often this step is all that's needed. split it into
17 Apr 2014 Whenever I make a lot of plots in R , I tend to make a multi-page PDF document. PDF is usually great: it's vectorized, which means it will scale no matter how much I zoom in or out. The problem with it is that for “large'' plots, which have a lot of points or lines, or just generally have a lot going on, the size of
30 Jan 2009 R always has a concept of the real-world dimensions of your graphic measured in inches, independent of the number of pixels used to render a PNG or the actual size a PDF may be enlarged or reduced to when printing. The choice of physical dimensions is important whenever you use text on graph
qpdf and/or gs_cmd are run on all PDF files found, and those which are reduced in size by at least 10% and 10Kb are replaced. The strategy of our use of qpdf is to (losslessly) compress both PDF streams and objects. GhostScript compresses streams and more (including downsampling and compressing embedded

6 Jul 2012 knitr - A general-purpose tool for dynamic report generation in R. The files look equal. However, if I re-run the last code but using pdf device option 'compress=FALSE', I get a file with size ~30MB. That made me suspect that maybe knitr was calling with compression deactivated, but that seems strange,
If it is NULL , then no external file is created (effectively, no drawing occurs), but the device may still be queried (e.g., for size of text). For use with onefile = FALSE give a C integer format such as "Rplot%03d.pdf" (the default in that case). (See postscript for further details.) Tilde expansion (see path.expand ) is done. width
