\end{enumerate}} \\ - issue ?

[aleksandar-spasojevic]

Hi there,

I'm trying to render this solutions.Rmd file:

---
title: "Solutions"
author: "Aleksandar Spasojevic"
date: "27. Juni 2014"
output:
  pdf_document:
    fig_crop: no
    keep_tex: yes
    number_sections: yes
    toc: yes

---

Test

render("solutions.Rmd", "pdf_document") produces:

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

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.67 \end{enumerate}} \\

pandoc: Error producing PDF from TeX source
Error: pandoc document conversion failed with error 43

A look into solutions.tex File solved the issue by deleting the \\ on line 67.

...
\begin{document}

\begin{center}
\huge Solutions \\[0.2cm]
\large \emph{Aleksandar Spasojevic}\\[0.1cm]
\large \emph{\begin{enumerate}
\def\labelenumi{\arabic{enumi}.}
\setcounter{enumi}{26}
\itemsep1pt\parskip0pt\parsep0pt
\item
  Juni 2014
\end{enumerate}} \\ % '\\' has to be removed for compiling
\normalsize
\end{center}
...

Is this an issue caused by rmarkdown or is my latex installation just stupid to neglect this newline 'operator' (excuse me for, somehow, latex questions)?

Cheers
Aleksandar

I believe this issue was caused by 27. -- the date was treated as an item in a numbered list. The pattern N. is for numbered lists, where N is a number. Two possible solutions:

• remove the period ., e.g. 27 Juni 2014
• or escape it 27\\. Juni 2014

solved the issue, thanks Yihui 👍

@jjallaire I was just told by a German user that the date field in YAML was formatted in the form 27. Juni 2014 in a newly created R Markdown document in RStudio IDE, and I have seen four such reports so far. The period after the day can cause problems with Pandoc/LaTeX. To be safe, I think we should format the day in YYYY-mm-dd or mm-dd-YYYY so we don't get unexpected characters in the day/month name.

I can confirm that this is the case and causes issues when trying to render the document. Escaping the period fixes the issue.

[jjallaire]

Okay, we'll make a change in RStudio to ensure that periods aren't
generated (or if they are they are escaped).

We can work around this on RStudio (we effectively use the default output from new Date() in JavaScript as the default); but is it possible to handle this on the rmarkdown side -- perhaps by escaping the date: field on render, or else wrapping it in a verbatim tag?

Hi there! I am also having problems producing a PDF from an .Rmd file (a google search led me here)
Error code:

Unknown program /Library/TeX/texbin/pdflatex
pandoc: Error producing PDF
Error: pandoc document conversion failed with error 43
Execution halted

Any help is much appreciated! I tried removing the data line in the header but it doesn't seem to help.

[yihui]

@jennaleeb Your issue is different. Please see #590.

[jennaleeb]

@yihui sorry about that, thanks!

[FelixZangerl]

Unfortunately the issue is still there. Is there a way to escape the dot when the date is generated via
date: r format(Sys.time(), '%d. %B, %Y')
?

Cheers
Felix

[yihui]

@FelixZangerl Yes, there is, but please either read my first reply above or ask the question on Stack Overflow or RStudio Community instead. Thanks!
