Q: How to change the distance between the title and the authors in the title page in foils?

Use vspace command in the author command. Example:

leftheader{textsc{Presentation using textsc{pdf}LaTeX, and FoilTeX, class}} %make a left header %rightheader{textsf{thepage}} %make a right header MyLogo{Eugenia and Weiliang, UBC Stats} %make a left footer %rightfooter{} %make a right footer title{shadowbox{Presentation using textsc{pdf}LaTeX, and FoilTeX, class}} % the document title % the author author{vspace{2cm}\r Latex Smart \r 6356 Agricultural Road\r University of British Columbia\r Vancouver BC \r V6T 1Z2} % the date date{today} begin{document} thispagestyle{empty} setcounter{page}{0} maketitle
Q: How to change the frame style of the slides in the "seminar" class?
A1) Method 1:
      a) first include "usepackage{fancybox}"
      b) then use
           slideframe{shadow} or
           slideframe{double} or
           slideframe{oval} or
         to change frame style or use
         to create slides without frame
     note: put these commands in the preamble will cause all slides have 
the same frame unless you use another slideframe command to change it.
The above commands can be used within any begin{slide}...end{slide}.

  Method 2:
    a) first include "usepackage{semcolor}"
    b) then use
      slideframe{scplain} or
      slideframe{scshadow} or
      slideframe{scdouble} or
Q: Several BibTeX style files for Stats magazines

Here . Rated as "very useful" by Weiliang. Problem is that some journals require bibliographic references in one's paper to be exactly as they want. This collection can help you to solve this problem much faster.

Q: How to let the cited references have the form "authors (year)" instead of "[1]" say?

You can use the package "natbib". The following is an example:

usepackage[super, sort]{natbib}
bibpunct{(}{)}{;}{a}{,}{,} % required for natbib


Use the natbib package with options texttt{super} and texttt{sort}, 
and use verb+citep+ or verb+citet+
instead of the command verb+cite+. In detail, we need to include the 
natbib package
and include the line

bibliographystyle[super, sort]{natbib}

in the preamble. 

And use the bibliographstyle texttt{plainnat}, i.e.

The command
verb+citet+ is for ``last name (year)'' and verb+citep+ for 
``(last name, year)'' which will be shown in the text.

The result of verb+citep{GoossensEtAl:1999}+ is citep{GoossensEtAl:1999}.
The result of verb+citetcitet{GoossensEtAl:1999}+ is citet{GoossensEtAl:1999}.

bibliographystyle{plainnat} % required for natbib


The content of the file "


" is below:

  author="{Goossens, M.} and {Rahtz, S.} with {Gurari, E., M.} and {Moore, R.} and {Sutor, R.  S.}",
  title="The LaTeX, Web Companion",

You can copy the above two files to your computer and compile them to see the



Q: How do you make a PDF document from a TeX/LaTeX formatted file?

To make PDF documents from a TeX or LaTeX source, use one of these commands:

         pdftex file.tex  ... or ...      pdflatex file.tex 

substituting file.tex for the filename of your TeX/LaTeX sources. The output ought to be be in

Q: Using pdflatex/pdftex/dvipdfm as part of teTex

Below are ways to get from TeX/LaTeX to a pdf file. These approaches are highly recommended over the use of ps2pdf, which does a bitmap conversion (resulting in a huge pdf file that is not searchable by words).

Converting latex: pdflatex without graphics

Just run pdflatex.

Converting latex: pdflatex with graphics

To include figures in latex, the "best" approach is with the graphicx package:




Then figures are included with something like



   \includegraphics[width=3in, height=4in]{plot}
   \includegraphics[width=7.5cm, height=10cm]{plot}

The use of \totalheight or \totalwidth is preferable in order that text characters are proportional and not squished in one direction.

Just run pdflatex or latex. For the above, pdflatex assumes a file plot.pdf exists, and latex assumes a file plot.ps exists

Converting figures as ps files to pdf: ps2pdf, epstopdf

To convert a figure from postscript (ps file) to pdf, use the ps2pdf command. If this fails, then try epstopdf. This conversion is needed to include graphics for pdflatex. In pdflatex, graphics types allowed are pdf and png, but not ps.

Converting dvi to pdf: dvipdfm

dvipdfm is currently only available on the Linux computers, not the Solaris computers.

dvipdfm converts a dvi file directly to pdf, without changes in the TeX/LaTeX file. The resulting file is searchable. Different graphics type (eg., jpeg, gif) can be used with the graphicx package in LaTeX; these cannot be seen with xdvi but they can be seen from acroread after the dvi file is converted to pdf.

Sometimes dvipdfm works better than pdflatex (e.g., slides using the 'seminar' style).

Q: Common TeX/laTex errors

This is a list of common TeX/LaTeX errors that I see when reviewing manuscripts. Also some shortcuts are given to make math equations more readable (and easier to edit).

Note the \def (or \newcommand) should appear at the beginning of your tex file (before \begin{document} in LaTeX).

  • If you look carefully at math writing, variables are printed in the italics or slanted font. However something like the exp or log function is not a variable, so it is in standard font, even within math mode. That is, \exp, \log, \sin etc are used for math and trigonometric functions. For statistics, \Pr is a definition for probability of an event, but \E for expectation and \Var for variance, etc, are not defined.

    However, you can define these yourself with something like

         \def\Var{\mathop{\rm Var}} 


         \def\Var{{\rm Var}\,}
         \def\E{{\rm E}\,}

    The first version does not work well for E.

  • Math expressions with subscripts and superscripts should also be put in math mode, e.g., $a$, $x=1$, $-1$. In non-math mode, - is a hyphen (shorter than minus sign, -- is an en dash (e.g. for pp. 34--43), and --- is an em dash — for use in a middle of a sentence.
  • Unless you are in displayed math mode, fractions should usually be expressed with a solidus, for example $x_i/n$ and not $\frac{x_i}{n}$ or ${x_i\over n}$.
  • Use a definition for any math symbol with a 'hat', 'bar', 'tilde' etc. This will make equations easier to read in TeX. Same thing for symbols for equal in distribution, convergence in probability, etc. Examples are:
        \def\phat{{\hat p}} 
        \def\Fbar{{\overline F}}
        \def\eqd{\,{\buildrel d \over =}\,} 
  • boldface Greek in scriptsize: LaTeX may not automatically resize a symbol when it is a subscript of superscript. Hence def are needed for scriptsize characters, e.g.
      \def\thbf{\mbox{\boldmath $\theta$}
      \def\thbfs{\mbox{\scriptsize \boldmath $\theta$}}
      $$f(\thbf) =2^{\thbfs}$$

    Alternatively, use the ams packages amsmath and amssymb

  • labelling of equations, and theorems, lemmas, corollary: 
    To get the section number to appear in an equation, add (to the beginning):

    and add


    at the beginning of each section.

    To get Theorems, Lemmas, Corollaries to be on the same numbering scheme, by section, add:

  • larger brackets[], braces{}, parentheses(): these should be used around summations, fractions etc. It is simplest to use \left[, \right] etc, but left and right only work if your equation is not split into more than one line. In the latter case, use one of \bigl, \Bigl, \bbigl, \Biggl (and corresponding \bigr on the right).

    Sometimes one needs a larger '/' or '|'. For '/', use \bigm, \Bigm etc. For '|', use \bigl, \bigm, \bigr etc depending on whether it is left, middle or right.

Q: How to wrap text around the figure or table?

You can use either floatflt package or wrapfig package.

For example:

\caption{Text wrap around figure}
\noindent \hrulefill


\caption{Text wrap around figure}
\noindent \hrulefill

The difference between floatingfigure and wrapfigure is that the text typed after end{floatingfigure} will be forced to be a new paragraph.

For more information, please refer to floatflt manual and a webpage about wrapfig.

Q: Writing thesis (PhD or MSc) in LaTeX

There is a class file for LaTeX2e that helps you produce a properly formatted UBC thesis. It's not officially supported by UBC but has been endorsed by FoGS as mentioned on their webpage. The download link can be found in the LaTeX section there.

Just in case the FoGS website is down here is a direct download link provided by Michael McNeil Forbes, the author of the class file and a former UBC graduate student.
