side by side figures

\begin{tabular}{cc}
\begin{minipage}
 		fjsdajfl
 	\end{minipage}
\begin{minipage} fasfd \end{minipage} 
\end{tabular}

Use subcaption

\begin{figure}[ht]
\centering
\begin{subfigure}{.5\textwidth}
\includegraphics[width=1\linewidth]{diffquantiley1.png}
\caption{Scatter plot of $Y_1$ and fitted quantile lines}
\end{subfigure}%
\begin{subfigure}{.5\textwidth}
\includegraphics[width = 1\linewidth]{diffquantiley2.png}
\caption{Scatter plot of marginal $Y_2$ and fitted quantile lines}
\end{subfigure}
\end{figure}

The % after subfigure is important to have side by side figures.

subfigure package

\begin{figure}
\hfill
\subfigure[Title A]{\includegraphics[width=5cm]{img1}}
\hfill
\subfigure[Title B]{\includegraphics[width=5cm]{img2}}
\hfill
\caption{Title for both}
\end{figure}

minipage

\begin{figure}
\centering
\begin{minipage}{.5\textwidth}
\centering
\includegraphics[width=.4\linewidth]{image1}
\captionof{figure}{A figure}
\label{fig:test1}
\end{minipage}%
\begin{minipage}{.5\textwidth}
\centering
\includegraphics[width=.4\linewidth]{image1}
\captionof{figure}{Another figure}
\label{fig:test2}

Number

Number a group of equations:

\begin{equation}
	\begin{aligned}
		w^T x_i + b &\geq 1-\xi_i &\text{ if }& y_i=1,  \\
		w^T x_i + b &\leq -1+\xi_i & \text{ if } &y_i=-1,
	\end{aligned}
\end{equation}

Citation

  • remove aux and bbl file to refresh

  • change bib file encoding with uft-8 by

      C-x RET f utf-8 RET

  • Code:

      \usepackage{natbib}
  \bibliographystyle{plainnat}
  \bibliography{\filename}
  • do not use the same file name for bib file

underline on journals

It is because the package ulem making emph to have underlines.

latexdiff with Git

http://tex.stackexchange.com/questions/1325/using-latexdiff-with-git

http://www.carlboettiger.info/wordpress/archives/3804

  1. create git-latexdiff in ~/bin/ and move to /usr/local/bin.

  2. update ~/.gitconfig

     [difftool.latex]
 cmd = git-latexdiff "$LOCAL" "$REMOTE"
 [difftool]
 prompt = false
 [alias]
 ldiff = difftool -t latex

  3. usage

     git ldiff HEAD
 git ldiff file
 git ldiff --cached file

A python script: http://www.numbertheory.nl/2012/02/09/scm-latexdiff-a-python-script-to-calculate-diffs-for-tex-files-in-git-or-mercurial-repositories/

Not work with sub directory:

To work with bibtex: move qr-missing-reference.bib to root directory

Tips

Using LaTeX to Split PDF Files

Suppose your source pdf is source.pdf, you wanna draw the 2nd and 4th page from that, by

\usepackage{pdfpages}
\includepdf[page={2,4}]{source}

pdflatex -> voila, here you are.

Titlepage and Cover

  1. http://blog.sina.com.cn/s/blog_5e16f1770102epls.html
  2. http://tex.stackexchange.com/questions/17579/how-can-i-design-a-book-cover

Break Long Equation

  1. http://stackoverflow.com/questions/1578127/how-do-i-break-a-long-equation-over-lines

  2. http://tex.stackexchange.com/questions/22573/how-can-i-tell-auctex-that-breqn-is-a-math-environment

    \documentclass{article} \usepackage{breqn} \begin{document} \begin{dmath} f(n)-f(0) = A(n)-B(n)-C(n)-D(n)\cdot d-\left(A(0)-B(0)-C(0)-D(0)\cdot d\right) = A(n)-0-X-D(n)\cdot d-\left(0-0-0-0\right) = A(n)-X-D(n)\cdot d \end{dmath} \end{document}

In order to turn on math mode in dmath environment:

(add-hook 'LaTeX-mode-hook 'add-my-latex-environments)
(defun add-my-latex-environments ()
(LaTeX-add-environments
'("dmath" LaTeX-env-label)))
;; Code I added to make syntax highlighting work in Auctex
(custom-set-variables
'(font-latex-math-environments (quote
("display" "displaymath" "equation" "eqnarray" "gather" "multline"
"align" "alignat" "xalignat" "dmath")))
'(TeX-insert-braces nil)) ;;Stops putting {} on argumentless commands to "save" whitespace
;; Additionally, reftex code to recognize this environment as an equation
(setq reftex-label-alist
'(("dmath" ?e nil nil t)))

Subfiles

http://tex.stackexchange.com/questions/11311/how-to-include-a-document-into-another-document/11318#11318

Try standalone, or subfiles packages.

For standalone:

% main.tex
\documentclass{article}
\usepackage{standalone}
\begin{document}
\include{B}
\end{document}

% B.tex
\documentclass{article}
\begin{document}
...
\end{document}

include and input

Input just copy and paste.

include break page

Use newclude package and use \include*{section}.

Multiple files

Put the following at the end of master file:

%%% Local Variables:
%%% mode: latex
%%% TeX-master: "dissertation"
%%% End:

or C-c _, then ref will automatically scan other sub files.

Table

Scale Table to fit on one page

Put \tabcolsep = 0.11cm before \begin{tabular}.

Subfiles

% Main.tex
% Preamble
\usepackage{subfiles}
% More preamble
\begin{document}
\subfile{Methods}
\subfile{AnotherSection}
\subfile{OtherStuff}
\end{document}

% Methods.tex
\documentclass[Main.tex]{subfiles}
\begin{document}
\section{Methods}
\end{document}

For bibtex, one solution from here

\documentclass[...]{...}
\usepackage{natbib}
\usepackage{subfiles}
...
\def\biblio{\bibliographystyle{plainnat}\bibliography{bibliography}}
\begin{document}
\def\biblio{}
...
\subfile{chapter\_1}
\subfile{chapter\_2}
...
\bibliographystyle{plainnat}
\bibliography{bibliography}
\end{document}

In chapter tex file:

\documentclass[main]{subfiles}
\begin{document}
...
\biblio
\end{document}

Bibtex

Where to get correct bibtex:

go to http://www.ams.org/mathscinet/index.html,

then clipboard, then export to bibtex together.
