For cairo, I used this header and same code as below. #+begin_src R :exports results :results output :type cairo
Running code block gives this output. #+RESULTS: : null device : 1 Now I can insert a link using [[file:figures/cairoplot.png]] Is it possible to input file name as header and have the code output graphics file link? Also, what are valid inputs for :antialias ? > On Apr 16, 2025, at 8:45 AM, Christian Moe <m...@christianmoe.com> wrote: > > Try this: > > :type cairo > > See: https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-R.html > > Yours, > Christian > > Naresh Gurbuxani <naresh_gurbux...@hotmail.com> writes: > >> How can I set up a code block which uses R code to output a cairo >> graphics file?
