I have a problem with images made by R code blocks in Org: not being displayed
or refreshed. (This has been going on for a while, but I can't remember when it
started.) Here's a minimal reproducible example I hope others can check. It
requires R on your system and the ESS package.
First, here's my minimal-init.el file:
#----- minimal-init.el
(setq debug-on-error t
debug-on-signal nil
debug-on-quit nil)
(add-to-list 'load-path (expand-file-name "/usr/local/src/org-mode/lisp"))
(org-babel-do-load-languages 'org-babel-load-languages '(
(R . t)
(shell . t)
))
(add-to-list 'load-path "~/.emacs.d/elpa/ess-20221121.1627") ;;
"/usr/local/src/ESS/lisp"
(require 'ess-r-mode)
# -----
For me this runs Org from the source tree (up to date today) and ESS from where
it was installed (package updated yesterday, as it happens). Adjust paths as
necessary.
Next, here is r.org, with one R code block that makes a simple chart:
# ----- r.org
#+begin_src R :results graphics file :file /tmp/plot.png :width 300 :height
300
plot(c(1, 2, 3, 4), c(1, 8, 27, 64))
#+end_src
# -----
Run Emacs:
$ emacs -Q -l minimal-init.el
In Emacs:
+ C-x C-f (load r.org wherever it is)
+ C-c C-c (to execute the R code)
+ Say yes to "Evaluate this R code block on your system?"
+ #RESULTS block appears (good) but image does not show
+ C-c C-x C-v (to toggle image display)
+ image appears
+ C-c C-c (to execute R code again)
+ Say yes to "Evaluate this R code block on your system?"
+ image disappears
+ C-c C-x C-v says "Inline image display turned off"
+ C-c C-x C-v says "Inline image display turned off" (and so on)
Expected behaviour: Images should appear when this code block is run or rerun,
and C-c C-X C-v (org-toggle-inline-images) should toggle the setting, not keep
it off.
Thanks,
Bill
