* default units for graphics in R code blocks @ 2020-03-30 15:44 Tyler Smith 2020-03-30 16:32 ` John Hendy 0 siblings, 1 reply; 5+ messages in thread From: Tyler Smith @ 2020-03-30 15:44 UTC (permalink / raw) To: Emacs Org-Mode Help Hi, The worg documentation for R code indicates the default units for graphics output is 'in', inches. However, when I try the following: #+begin_src R :results file graphics :file ca.jpg :width 8 :height 11 plot(1:10) #+end_src I get an error noting the margins are too large. If I change the width and height arguments to 800, it works just fine, and the resulting image is pretty small. I can also get a working image by specifying units as in and res as 100. I conclude from this that the default units are actually pixels? Is that correct? If so I can update the docs.

When you examine the properties of this "pretty small" resulting image, is the size equal to 800 x 800px? > I can also get a working image by specifying units as in and res as 100. > > I conclude from this that the default units are actually pixels? Is that > correct? If so I can update the docs. I'd have to look deeper/test to confirm, but believe the units are according to the output device. I'm near certain, for example, that PDF output is in inches. I think png and jpg may both be px. It may not be consistent/universal is my point! Edit before sending: Best to cite exactly which article you're referring to. Trying to look myself, for example, found me this as the only worg hit from googling "worg R plotting": - https://orgmode.org/worg/org-tutorials/org-R/org-R.html """ Output options height:1000set height of graphical output in (pixels for png, jpeg, bmp, tiff; default 480) / (inches for pdf, ps; default 7) width:1000set width of graphical output in pixels (default 480 for png) """ It seems that aligns with my recollection, but may very well differ from the article you found.

Sorry about that. Thanks for your efforts. I find org documentation challenging at times, and am still not clear on worg vs. org. I believe I've asked on this list before why those pages exist, as this seems like it should be in the org official docs vs. in a sort of tutorial site. It makes it tough as you can't find certain header args in the org docs; you have to kind of know what you're looking for, or at least that the header arg is *only* for, say, R, and not for anything else. Anyway, thanks for contributing!

I think it might be useful to consolidate and delete as much as possible, but that's going to be a lot of work. The existence of a page called "Library of Babel", https://orgmode.org/worg/library-of-babel.html that doesn't actually refer to org-babel seems especially misleading! In any case, I updated ob-doc-R with the correct info.
