[Tex/LaTex] How to format only one section of RMarkdown pdf output using sectsy

markdownsectsty

I am creating a pdf using R-markdown. I want ALL section headings to be centered (using sectsty package),except the first one which should be left aligned. How can I do this ? How do I use sectsty for only one section ?

Here is a minimal working example :

---
date : 2018-April-25
output:
    pdf_document:
toc: true
toc_depth: 1
title: "Test document"
fontsize: 12pt

header-includes:
- \usepackage{booktabs}
- \usepackage{sectsty} \allsectionsfont{\centering}
---


\sectionfont{\left}

## This is a heading

## This is a second heading.

Best Answer

What you tried didn't work because the \left macro is a mathmode macro for making an extensible left delimiter. Your document should have generated an error if compiled, but maybe it gets hidden from you.

Try the following:

---
title: "secsty-test"
date: "4/25/2018"
output: pdf_document
header-includes:
- \usepackage{booktabs}
- \usepackage{sectsty} \allsectionsfont{\centering}
---
\allsectionsfont{\raggedright}
## This is a heading

\allsectionsfont{\centering}
## This is a second heading.

You can do this more simply by defining a personal command. This is the simplest way:

\newcommand{\problem}{%
  \refstepcounter{section}%
  \section*{Problem \thesection}}

Here's a skeleton document:

\documentclass{article}

\usepackage{amsmath}

\newcommand{\problem}{%
  \refstepcounter{section}%
  \section*{Problem \thesection}}

\numberwithin{equation}{section}

\begin{document}

\problem\label{easy}

Compute the following expression:
\begin{equation}\label{compute}
1+1
\end{equation}

\problem\label{difficult}

Using the result obtained from~\eqref{compute} in Problem~\ref{easy}, 
express
\begin{equation}
\int_{0}^{x} e^{-t^2}\,dt
\end{equation}
in terms of elementary functions.

\end{document}

There are many possible refinements. For example, you seem to want to have sequences of problems. Here's an attempt at it:

\documentclass{article}

\usepackage{amsmath,xparse}

\NewDocumentCommand{\problem}{ s }
 {%
  \IfBooleanTF{#1}
   {\refstepcounter{subproblem}%
    \section*{Problem \thesubproblem}}%
   {\refstepcounter{section}%
    \section*{Problem \thesection}}%
 }


\newcounter{subproblem}[section]
\renewcommand{\thesubproblem}{\thesection\alph{subproblem}}
\numberwithin{equation}{section}

\begin{document}

\problem\label{easy}

Compute the following expression:
\begin{equation}\label{compute-easy}
1+1
\end{equation}

\problem*\label{less-easy}
Compute the following expression:
\begin{equation}\label{compute-less-easy}
1-1
\end{equation}

\problem\label{difficult}

Using the result obtained in~\eqref{compute-easy} and 
Problem~\ref{less-easy}, express
\begin{equation}
\int_{0}^{x} e^{-t^2}\,dt
\end{equation}
in terms of elementary functions.

\end{document}

A “main problem” is started with \problem, while a “subproblem” is started with \problem*. The equation number will still be the one established by the main problem.

Avoiding the explicit number in the command allows for easily change the order of the problem, by just shuffling around their texts.

[Tex/LaTex] Knitr and rmarkdown will not add figure captions to the output

Try adding fig_caption: yes to the YAML header of your .Rmd file. It will look something like this:

---
title: "Untitled"
author: "Nicholas"
date: "20/09/2014"
output:
  pdf_document:
    fig_caption: yes
---
