org-babel strange html print in R

org-babel strange html print in R

[Jeremie Juste]

Hello,

I've found that some strange results when outputing html from R.
Do you have some insights on a potential solution?

Best regards,
Jeremie

On my system, org-mode 3.6.1 provides the expected table.

This seems to be a *very* version of org-mode ;)

Bummer... I remember that I've used org-version to get the version number. I 
guess I have cut'n'pasted an unrelated number :-/

For the record, I've tested R and html output on Org mode version 9.3.1

Sorry for the confusion.

All the best

My system produces the expected table as well (org 9.3.2, R 3.6.2).

Thanks for the info. 
Unfortunately I couldn't identify the issue
I updated R and org (org 9.3.2, R 3.6.2).

Sorry, I missed the initial property line where you set the ":session"
header argument.

When I set the ":session" header argument, I get the original buggy
behavior that you report.

It looks like the reason for this, is that the substrings like "tr>"
match `comint-prompt-regexp', and so get stripped out by
`org-babel-comint-with-output'.

I think a more reliable implementation would be to avoid
`org-babel-comint-with-output', and take the approach used in the
":results value" case, which reads the output from a temp file instead
of directly from the shell.

Actually, that's the approach I use in my ob-session-async package [0],
which re-implements ob-R sessions to allow async evaluation. It doesn't
suffer from the bug you are reporting. I'll plan to extract that
implementation and submit it as a patch here.

Long term, I am intending to contribute the full functionality in
ob-session-async here, but that's still a ways off.

I understand better now. Thanks

Your solution works just fine. I came across ob-session-async a recently
and find it very interesting thanks again.

You should try ~:results value html~. Here is what I got correctly:

#+begin_src R :results value html
library(xtable)
x <- rnorm(100)
y <- x + rnorm(100)
print(xtable(summary(lm(y ~ x))),type="html")

Yes, this seems like the best solution for this case.

On the other hand, it would be desirable if ":results output" didn't
mangle the output, due to trying to clean up prompts. There is probably
some corner case out there where this is a more serious issue -- but for
this case, it seems best to just use ":results value html".

I was planning to submit my implementation of ":session :results output"
that avoids the prompt mangling [0], but now I'm leaning towards putting
this off, until a more compelling case arises to justify it.

Hello,

Thanks for the input.
I didn't see the full mail of stardiviner for some reason.

:results value html  in the following code generates an error for me.
(Org mode version 9.2.3,R version 3.6.2).
but :results value output the "html" in an org-table format

#+begin_src R :results value html
library(xtable)
x <- rnorm(100)
y <- x + rnorm(100)
print(xtable(summary(lm(y ~ x))),type="html")
#+end_src

Best regards,
Jeremie

Hmm, I can confirm that ":session :results value html" is working for
me, same as for stardiviner. Could you give more info about the error
you're seeing?

I'm using R 3.6.2 and Org 9.4. But I'd be surprised if it doesn't work
for Org 9.2 -- git blame suggests that html output has been supported in
ob-R since at least 2015. But it wouldn't hurt to upgrade to the latest
released version of Org (9.3).

About this, I found Gmail put my emails into Spams folder. I can't figure out
what reasons. I also found similar situations in some people in Emacs-help guys.
Anyway, If you can, please report my emails "Not Spam". Thanks :)
