tinytex | maintain LaTeX distribution based on TeX Live

I had the same issue and it seems you will need to pass the absolute path. See this .

Instead of using here maybe try using normalizePath in include_graphics.

So omit your call here(), which may not be propagating across chunks (I don't know, because I can't see your chunks), and do:

The percentage values are converted into character with the cell_spec argument. with a bit of stringr and regex the decimal values can be converted to percentages. Note % is a reserved symbol in LaTeX so needs escaping.

Using dplyr::mutate(across... and max(c_across... is one way:

You can do this with my huxtable package:

The problem is completely unrelated to any r libraries. The reason why you only see it if you fix the r errors is that then your document is more than one page long and you actually get to see your fancy headers (the first page uses a different pagestyle, thus no error with only one page).

As the error messages says, the actual problem is that \theauthor is not defined. You manually define it for the title, you must also define it for the author.

I found a book on the Papaja package. That link will bring you to the YAML section. I think this is what you were looking for.

First, there doesn't appear to be an association for APA 7, unless you have the development version of Papaja. That being said, there is a ticket on this in their main github.

If you set the output to apa6_docx, this "and &" error won't be there. (And even if it were, you could have deleted it.) You can save it as a PDF from there. I'm not sure if this is an option for you, but I thought I would mention it.

This is what it states about subsequent authors (and much more).

You should do this:

Remove the default keyword:

There are numerous ways to achieve this.

PDF/LaTeX-only

If you need PDF output only you may use a LaTeX package that supports lowercase calligraphic letters in math mode, e.g. dutchcal.

Since this is not tex.stackexchange and you mention that you're not too familiar with Tex, I'm not going too much into detail. Here's a simple example of a PDF rmarkdown project:

1. Set up a file preamble.tex:

   \DeclareMathAlphabet{\mathdutchcal}{U}{dutchcal}{m}{n}

   This ensures that dutchcal letters are used in math mode using \mathdutchcal{}.

2. Ensure that the content of preamble.tex is included in the tex file from which the PDF will be generated by setting up the yaml header of your .rmd file accordingly:
