Archive done tasks and preserve tree structure
In my task list, items are grouped under various headings. For example: * Reading ** TODO Book 1 ** TODO Book 2 * Programming ** TODO assignment 1 ** TODO assignment 2 When an item is DONE, I want to archive it such that archive file preserves tree structure. So when Book 1 above is DONE, I want C-c C-x C-a to send this subtree to archive file under the heading Reading. I followed the suggestion here: https://stackoverflow.com/questions/10143959/keeping-the-context-when-archiving-in-emacs-org-mode My updated tasks file looks like this. * Reading :PROPERTIES: :ARCHIVE: %s_archive::Reading :END: ** TODO Book 1 ** TODO Book 2 Adding this property does not change archive action. After marking Book 1 as DONE, then typing C-c C-x C-a sends this subtree to archive file as a top level heading. As a result, my archive file has a long list of top level headings. How can I get the archiving done to preserve tree structure of tasks? Any hope for already archived items to be reorganized? Thanks, Naresh
Org agenda view does not display correctly
Until recently, my org agenda view displayed correctly. Now M-x org-agenda a display begins with question marks. Is there a simple way to diagnose and fix this problem? I am using org mode version 9.6.6 (default) in emacs version 29.1 on mac.

Re: Emacs and org mode in aws
I understand that, in terminal, images are not displayed in emacs. Are people using other ways to connect to aws where they can see images in emacs?

Emacs and org mode in aws
In my Amazon Web Service account, I can launch emacs from the terminal. Nearly all emacs features work well. But I miss the ability to view graphs created by code blocks in org mode. Have other members found a solution? Thanks, Naresh
Re: R code blocks in org version 9.5
It seems that org 9.5 has simplified header arguments for R code blocks that use grid graphics. Org 9.4 requires :results output graphics file Org 9.5 requires :results output file Do other users find the same change?

Re: R code blocks in org version 9.5
Thanks to your suggestion, I was able to narrow down the problem. My R code blocks work fine in org 9.5. When I plot graph using base graphics in session, it works fine. The problem is with lattice graphs. With below header variables, code block works fine. #+begin_src R :session *R* :results graphics file :file test.png library(lattice) print(histogram(rnorm(1))) #+end_src But this does not work. Emacs hangs. #+begin_src R :session *R* :results output graphics file :file test.png library(lattice) histogram(rnorm(1)) #+end_src I can simply add print command to my code blocks. Is there an easier solution?

R code blocks in org version 9.5
Recently I started using org version 9.5 with my init.el that worked well for org 9.4 In org 9.5, I can run stand-alone R code blocks. But when I try to run them in a session, emacs hangs. Have you seen this problem? Is there a solution? Thanks, Naresh Sent from my iPhone

Efficiently reuse code in org babel with R
I want to source some data from databases, then use this data in various blocks. I am looking for the most efficient way to achieve this. In below blocks, is the code in block ``connection'' executed thrice (economy of code but no saving of time) or is it only executed once then used twice? If the code is run thrice, is there another way to create code blocks so that the code is executed only once? Thanks, Naresh #+name: connection #+begin_src R :exports results :results output ## my code here #+end_src #+begin_src R :exports results :results output graphics file :file figures/fig1.png <> ## my code here #+end_src #+begin_src R :exports results output graphics file :file figures/fig2.png <> ## my code here #+end_src

org-babal-R-command
In my windows computer, R is installed at c:/Program Files/Microsoft/R Open/R-3.5.1/bin Notice two spaces: “Program Files” and “R Open” How can I set the variable org-babel-R-command? I tried (setq org-babel-R-command “c:/Progra~1/Microsoft/R Open/R-3.5.1/bin/R.exe —slave —no-save”) But the space between R and Open is a problem. What is the solution?
