Greetings,
I'm wondering how to align the results from the R buffer (which I
like) vs. the results printed by Org-mode for table results. Here's a
toy example:
#+begin_src R :session foo :output results :type table :results value
library(tibble)
tmp <- tibble(x=1:5, y=x/pi)
tmp
#+end_src
In org, I get this:
#+RESULTS:
| 1 | 0.318309886183791 |
| 2 | 0.636619772367581 |
| 3 | 0.954929658551372 |
| 4 | 1.27323954473516 |
| 5 | 1.59154943091895 |
In the buffer, I get this:
x y
<int> <dbl>
1 1 0.318
2 2 0.637
3 3 0.955
4 4 1.27
5 5 1.59
From the tibble side, R points one to the pillar package[1], which
indeed affects the output in the buffer, but not in the Org results.
#+begin_src R :session foo :output results :type table :results value
library(tibble)
library(pillar)
options(pillar.sigfig=1)
tmp <- tibble(x=1:5, y=x/pi)
tmp
#+end_src
# A tibble: 5 × 2
x y
<int> <dbl>
1 1 0.3
2 2 0.6
3 3 1.
4 4 1.
5 5 2.
The last example here touches on accomplish this[2]... but is the only
method to write an elisp block that post-process my R results? It
seems so enticing that R can output the correct format... can Org
latch onto the exact output somehow?
I also discovered the round_df package[3], so I could bring that into
the mix and round flexibly, it seems. I don't *really* want to round,
though, I just want more digestible output.
Many thanks for any pointers, I'm suspecting the answer is before my
eyes, but I haven't figured out the proper incantation of :results,
:type, :wrap, etc...
Best regards,
John

`tbl_df' objects come with their own print/show method. And it does things like add color and text formats. This is nice in a terminal, but not when you want to display them in org.
Turning off the color might be enough to give you a usable result:
#+begin_src R :session foo :results output drawer
library(tibble)
options( cli.num_colors=1 )
tmp <- tibble(x=1:5, y=x/pi)
tmp
#+end_src
#+RESULTS:
:results:
# A tibble: 5 x 2
x y
<int> <dbl>
1 1 0.3
2 2 0.6
3 3 1.
4 4 1.
5 5 2.
:end:
If this is not close to what you need, I suggest writing your own formatting function. If you have limited emacs-lisp skill, I suggest doing this in R.
HTH,
Chuck

Interesting, and thanks for taking a look. I don't think I specified
sufficiently that I'm actually aiming for latex/pdf output and
therefore want the org table. I can just add my own header row and get
booktabs formatting free upon export. If I keep with :results output,
the color options trick does remove a bunch of garbage from the
output... but :results value still yields:
#+RESULTS:
| 1 | 0.318309886183791 |
| 2 | 0.636619772367581 |
| 3 | 0.954929658551372 |
| 4 | 1.27323954473516 |
| 5 | 1.59154943091895 |
I was hoping there was a way to either (a) have org post-format or (b)
take the results as printed. I'm not sure on the exact mechanism used
which creates the mismatched output in the session vs. the table. I
get that behind the scenes I still have long, irrational numbers
here... it's just that if org can print them with x decimal places, is
there some way to get Org to intercept *those* values?

John,
If you want a latex export, you should use one of the many R packages[1] that format R objects for latex output.
For example:
#+begin_src R :session foo :results output latex
library(tibble)
library(xtable)
tmp <- tibble(x=1:5, y=x/pi)
xtable(tmp)
#+end_src
#+RESULTS:
#+begin_export latex
% latex table generated in R 4.1.0 by xtable 1.8-4 package
% Sat Aug 21 10:23:18 2021
\begin{table}[ht]
\centering
\begin{tabular}{rrr}
\hline
& x & y \\
\hline
1 & 1 & 0.32 \\
2 & 2 & 0.64 \\
3 & 3 & 0.95 \\
4 & 4 & 1.27 \\
5 & 5 & 1.59 \\
\hline
\end{tabular}
\end{table}
#+end_export
The xtable() and its print method have loads of options for formatting, setting environments and labels, and adding captions.
If you insist on doing this in org without the assistance of an R package, you will need to use a `:post' header argument. If you have solid elisp skills, this is a viable option.
HTH,
Chuck

Hello, John
For my workflow, I generally use the minimum from xtable and do the
formatting in org-mode using the :post parameter to call another lisp code
block.
That said, as Chuck said, you can go a long way with xtable. In my
attic, I found the following code where I take only the core data from
xtable and do formatting in org-mode. This code may be a little
extravagant on the latex side but, it shows the possibilities.
HTH,
Jeremie
