Subject: Number format for table results outut from R data.frame/tibble
Date: Fri, 6 Aug 2021 10:38:09 -0500	[thread overview]
Message-ID: <CA+M2ft_iE4Gd9vXkEV9rmShY7-GBfQHY7Fpc2y99E6W4pHRC_w@mail.gmail.com> (raw)

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
