Since yesterday, I get a confusing error, when trying to knit my Markdown files to PDF. I get this warning:

This is pdfTeX, Version 3.141592653-2.6-1.40.24 (TeX Live 2022) (preloaded format=pdflatex)
 restricted \write18 enabled.
entering extended mode
I was unable to find any missing LaTeX packages from the error log Chapter-5-1.log.

The problem seems to be the kable tables, which have been knit in prior tries just nicely. In the error log, this is printed:

Overfull \hbox (165.80571pt too wide) in paragraph at lines 142--158
 [][] 
 []

l.158 \end{wraptable}

A friend of mine tried to compile the tex file directly to PDF, but got the same error. We where not able to find a missing } or any other error in the coding. All tables and code is running without error in the markdown preview.

I get the same error, when I try to knit a document with a dummy table, so I hope that works as a reproducible example.

R studio and tinytex are updated. I tried all the debugging tips and uninstalled and installed tinytex new. The same error is also happening when I try to knit on another computer. I also tried to change from xelatex to pdflatex but the error was the same.

CodePudding user response：

The wrapfig package does not particular like zero width wrapfigure or -table environments with captions. The package documentation has the following to say about the topic:

[...] However, if you specify a width of zero (0pt), the actual width of the figure will determine the wrapping width. A following \caption should have the same width as the figure, but it might fail badly; it is safer to specify a width when you use a caption.

You can avoid the problem by choosing a suitable width:

@samcarter_is_at_topanswers.xyz Your suggestion helped, the PDF is generated, but now the tabels are positioned very akwardly in the text (like in the image). I still don't get, why the compiling failed, when it worked just fine on its own before and I haven't changed anything in the coding or the packages involved. enter image description here
