无法使用自定义样式编织为pdf

Question

尝试使用自定义mystyles.sty文件从RStudio编织为pdf.这曾经工作正常,但现在我已升级到RStudio 1.044我得到一个错误.

例:

---
title: "Test"
output:
  pdf_document:
    includes:
      in_header: mystyles.sty
---



## 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:

```{r cars}
summary(cars)
```

使用此样式文件:

\usepackage{titlesec}

\definecolor{airforceblue}{rgb}{0.36, 0.54, 0.66}
\definecolor{coolblack}{rgb}{0.0, 0.18, 0.39}

\titleformat{\title}
{\color{airforceblue}\normalfont\Large\bfseries}
{\color{airforceblue}\thesection}{1em}{}
\titleformat{\section}
{\color{coolblack}\normalfont\Large\bfseries}
{\color{coolblack}\thesection}{1em}{}

给我这个错误:

output file: test.knit.md

! Argument of \paragraph has an extra }.
<inserted text> 
                \par 
l.1290 \ttl@extract\paragraph

pandoc: Error producing PDF
Error: pandoc document conversion failed with error 43
Execution halted

如果我查看它生成的tex文件,我看不到任何丢失的大括号,并且没有1290行.这是使用最新版本的RStudio,R和MacTex.正如我所说,这曾经与旧版本的RStudio一起使用,但不多了.如果我拿出包括:......在YAML之外,它会毫无怨言地呈现.有人能帮忙吗？

问题与rmarkdown乳胶模板的重新定义有关\subparagraph{},这种方式不同titlesec,正如tex.SE上的这个答案所暗示的那样.这是导致问题的模板的一部分:

$if(subparagraph)$
$else$
% Redefines (sub)paragraphs to behave more like sections
\ifx\paragraph\undefined\else
\let\oldparagraph\paragraph
\renewcommand{\paragraph}[1]{\oldparagraph{#1}\mbox{}}
\fi
\ifx\subparagraph\undefined\else
\let\oldsubparagraph\subparagraph
\renewcommand{\subparagraph}[1]{\oldsubparagraph{#1}\mbox{}}
\fi
$endif$

由于\subparagraph重新定义仅在没有子变量集的情况下发生,因此一个简单的解决方法是在yaml前端设置它.编译好:

---
title: "Test"
output:
  pdf_document:
    includes:
      in_header: mystyles.sty
subparagraph: true
---

但这可能不是最佳解决方案:最好从模板中修复子段定义.
