Error when knitting the .Rmd template - `xelatex` not found

[beatrizmilz]

Hi! I want to write my submission to LatinR 2020. I installed the package {latinr}, and then I created a new rmarkdown file from the template "LatinR Submission Article".

But when I tried to knit the document, I get this error:

Erro: LaTeX failed to compile submission.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips.
Além disso: Warning message:
In system2(..., stdout = if (use_file_stdout()) f1 else FALSE, stderr = f2) :
  '"xelatex"' not found
Execução interrompida

I looked up on google about this error message, and found this issue.

I tried to reinstall tinytex with tinytex::install_tinytex(), but I still get the error message.

Aparently tinytex is installed:

  tinytex::tinytex_root()
[1] "C:\\Users\\beatr\\AppData\\Roaming\\TinyTeX"

Do I need to install something else to use xelatex??

This is my session info:

Hi! Were you able to compile the skeleton document? That is, this RMarkdown?

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)

Including Plots

You can also embed plots, for example:

plot(pressure)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.[@Nuncio2011]

Hi! Yes, I'm trying to compile this exact Rmarkdown when I get this error!

[eliocamp]

Ah, sorry. I missed that in your original post. Have you tried using

output: 
    latinr::latinr_article:
      keep_tex: false
      latex_engine: pdflatex

as output?

[beatrizmilz]

Just tried it! But got another error.

Erro: LaTeX failed to compile submission.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips.
Execução interrompida

Is it needed to install anything else in the computer in order for it to work? I have MikTex installed

Thank you!

[beatrizmilz]

I'm trying to debug using these debugging tips, so If anything works I'll write here!

[eliocamp]

Ok, then xelatex is not the issue here. I've never used rmarkdown + LaTeX on windows so I don't know exactly how it works. But in any case, tinytex should work!

If you try to compile a pdf from just the normal rmarkdown document, what do you get?

Thanks! For some reason, compiling this code that you posted took some time, but it worked (generated a pdf).. Then I tried again to knit the submission template, and then R started installing some packages related to LaTeX. Exemple:

Trying to automatically install missing LaTeX packages...

It took some time but now works!!

Thank you so much!!

One question: in the footnote it says LATINR 2019. How do I change the footnote to say 2020?

[eliocamp]

That's weird.. 🧐️ But in any case, I'm glad everything's resolved. Thanks for the heads up on the footnote, I'll change it and update it!
