! LaTeX Error: There's no line here to end.

[frankbach]

This error message is produced by knit when I try to convert an Rmd file to pdf. I had updated all my packages before my attempt.
YAML looks like:

---
title: "Proven i religionskunskap"
author: "Frank Bach"
date: "`r Sys.Date()`"
bibliography: reference.bib
biblio-style: apa-like
csl: university-of-gothenburg-apa-swedish-legislations.csl
toc: FALSE
tables: yes
output:  
  bookdown::pdf_document2
lang: sv
header-includes:
 \usepackage{booktabs}
 \usepackage{longtable}
 \usepackage{array}
 \usepackage{multirow}
 \usepackage{wrapfig}
 \usepackage{float}
 \floatplacement{figure}{H}
---
and the r setup

```{r setup, include = FALSE}
library(papaja)
library(tidyverse)
library(readr)
library(lavaan)
library(scales)
library(psych)
library(semPlot)
library(equaltestMI)
library(semTools)
library(kableExtra)
library(gridExtra)
library(broom)
library(gt)
knitr::opts_chunk$set(
  echo = FALSE,
	warning = FALSE,
	cache.extra = knitr::rand_seed,
	out.extra = ""
)
set.seed(42)
options(OutDec= ",")
theme_set(theme_apa())
```

I was able knit the document as pasted above:

I had to comment out the lines:

bibliography: reference.bib
csl: university-of-gothenburg-apa-swedish-legislations.csl

As I do not have those files. I also had to add library(jtools) to your list for the theme_apa() function.

This suggests that there is something else in your .Rmd file that is triggering this latex error. I have gotten this error before, but I forget what it was caused by or how I fixed it.

One thing that caught my eye is:

biblio-style: apa-like

I generally just type this as apalike -- something to try for sure, but I don't anticipate this fixing the problem.

Another thing that could cause this problem, is the header-includes part. I generally use:

header-includes:
  - \usepackage{booktabs}
  - \usepackage{longtable}

Rather than omitting the hypens as you have done. I would try this too.

If neither of these solutions fix your problem, I suggest trying to dive into the log file to find which line specifically is causing your problem. You could then paste a more complete .Rmd file that users can reproduce the error from.

Thank you for your help, it got me to dive in to the log file and I finally found the error without really understand it. I just erased the part and built it up from the beginning. Then it worked.

Best regards

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
