elegantbookdown output to pdf

I want to know why i can output html but can not output pdf with elegantbookdown template.

and without elegantbookdown i can output pdf.

and in one situation(project), there is error following

Error in yaml::yaml.load(..., eval.expr = TRUE) :
Scanner error: while parsing a quoted scalar at line 2, column 9 found unknown escape character at line 2, column 41
Calls: ... parse_yaml_front_matter -> yaml_load ->

And when i chose annother project, i find it is ok to touch "knit to pdf", but it is just run to html

There is my version

Hi @fanzheng0352 ,

Will you share the YAML for your project so we can see where it is you're specifying the pdf output?

Here's the YAML example from the bookdown documentation:

---
documentclass: book
bibliography: [book.bib, packages.bib]
biblio-style: apalike
---

I think also you need to call the pdf_book() function, so your inputs there would also help troubleshoot.

Here's the example of that from bookdown:

pdf_book(toc = TRUE, number_sections = TRUE, fig_caption = TRUE,
  pandoc_args = NULL, ..., base_format = rmarkdown::pdf_document,
  toc_unnumbered = TRUE, toc_appendix = FALSE, toc_bib = FALSE,
  quote_footer = NULL, highlight_bw = FALSE)

And the link to that documentation

Thanks

Thanks @jonesey441 .

I just used the following template

@fanzheng0352 ,

I see, have you tried selecting the "Build" tab in RStudio, and then selecting "Build All"?

Try that and let me know what output you get.

This means something is not correct in the YAML syntax.

You should share you YAML file and headers so that we can help spot it.
