This is not a problem of the text content. When you create a points plot in R, it puts the information about all the points in the exported PDF figure, even if many of them correspond to the same coordinates. It does not « flatten » the pdf figure. When you plot millions of points, that results in a lot of information and may necessitate considerable amount of memory from the computer for displaying on the screen or from the printer, to transfer on paper. When we export to a bitmap format like PNG, the information is « flattened » and all points that fall on the same pixels are coded just the value of these pixels. That makes the figure easier to handle.
When you do a curve plot (like a density plot, for example) this problem does not exist. This is another strategy that I use when possible: can I show the same informed with a curve instead of with dots? If yes, I go for it. It is much more parsimonious. Using a bitmap format with correct proportions and sufficient density, the first solution gives very satisfactory results even if the figures are bitmaps. -- Prof. Murat Yildizoglu > Le 9 déc. 2021 à 00:37, Steve Litt <sl...@troubleshooters.com> a écrit : > > Rich Shepard said on Wed, 8 Dec 2021 07:51:56 -0800 (PST) > >> On Wed, 8 Dec 2021, Dr Eberhard Lisse wrote: > >>> For my big handbook (which takes 110 seconds to compile (70 on the >>> M1)) I have split this into child documents which compile >>> individually within 10 to 15 seconds. >> >> How about loading a PDF image that's 3,704,503 bytes in size while >> reading your big handbook? > > OK, 3,704,503 bytes got my attention.
