Errors in Bookdown after updating R 4.3.0

[selfaddicted]

Describe the bug
Failed to load the pkg in book down environment
the error message is as below

Error: package or namespace load failed for 'kableExtra':
.onLoad failed in loadNamespace() for 'kableExtra', details:
call: !is.null(rmarkdown::metadata$output) && rmarkdown::metadata$output %in%
error: 'length = 2' in coercion to 'logical(1)'

To Reproduce

1. Create a bookdown project
2. Call library(kableExtra) in a Rmd file
3. Build the project

it's too simple to reproduce.
when I rolled back R to 4.2.3 and the error was gone.

I have the same problem.
I have updated to R 4.2.3 and uninstall and install the latest version of kableextra, with install.packages and with devtools and I had same message when I runned knit to word.

Any solution??

Thanks in advance

Same issue here on R 4.3. Does downgrading to 4.2.3 help?

I installed the patched version from @kupietz and it works, see his comment for more information

I have noticed several issues with the new version of R that caused conflicts for me.
Previously, I had the following line: 'options(OutDec = ",")' that I have removed.
In terms of the output format, I used to have the following header:

output:
pdf_document:
toc: yes
toc_depth: '6'
bookdown::pdf_document2:
toc: yes
toc_depth: '6'
word_document:
toc: yes
toc_depth: '6'
html_document:
toc: yes
toc_float: yes
toc_collapsed: yes
toc_depth: 6
number_sections: yes
theme: lumen

However, if I change it and leave only the following for the 'word_document' output format:

output:
word_document:
toc: yes
toc_depth: '6'
I was able to solve my conflicts with the new version of R. I hope this solution is helpful to other users who may be experiencing similar issues."

Could I do this? How can I installed the patched version?
Thanks in advance

[oldiya]

In the comment, he suggested doing

devtools::install_github("kupietz/kableExtra")

This works for me.

[update: restarting the rsession after installing the dev version also corrected this issue, see below.]

I got the same error knitting an existing .Rmd file to html after upgrading to 4.3.0

The dev version from @kupietz did not solve the problem, but deleting the following header lines from my file;

output:
  html_document: default
  pdf_document: default

avoided the error.

Can you tell me the error message you got and have you restarted your R session after installing kupietz/kableExtra?

[rhurlin]

I don't think you really need to restart your R session. The following should do the trick:

detach(package:kableExtra)
library(kableExtra)

[kjewell]

My apologizes. I reinstalled the dev version and then restarted the r session and the error was avoided. i must not have restarted last time.

Ok, ran into the same/similar issue again on another file, using the @kupietz dev version.

error:

Quitting from lines 8-10 (test_output.Rmd)
Error: package or namespace load failed for 'kableExtra':
.onLoad failed in loadNamespace() for 'kableExtra', details:
call: if (!is.null(rmarkdown::metadata$output) && names(rmarkdown::metadata$output)[1] %in%
error: missing value where TRUE/FALSE needed
Execution halted

Here, the difference seems to be that the output was defined using slightly different syntax:
output: html_document

To Reproduce
Create a markdown file with the following content:

---
 output: html_document
---
 
{r setup, include=FALSE}
library(kableExtra)

knit the file.

Deleting the
'output: html_document'
line resolves the issue.

Thanks for the report! I've fixed the problem in kupietz/kableExtra and in PR #751 via c50a4cc .

[felipejuan]

Once I installed the patch from @kupietz, I had an issue with the kable_styling function, where the function is not found in the patched version once I try to knit the file. I've tried deleting the file outputs and restarting sessions when I apply these changes.

[go4ino]

I have a similar issue in r 4.3.1 when trying to knit a pdf / html / word document.

When I knit the document and leave out library(kableExtra), it renders just fine.

Does the switching to the dev version of the library fix this?

@kupietz Thanks, that worked!
@haozhu233 Is this still maintained?

I am using Fedora COPR R archive. I have to install the Github version because the COPR version is still 1.3.4.
