### Equation referencing in Word 2007

It baffles me that something so essential is not simple with micro$oft word. If you are going to want to put equations in your document, of course you will want to talk about them! (Otherwise, why bother?) To talk about them, of course you will need to reference them and the best way of doing that is with numbers. Why then is there no simple way to do this? Why give an equation tool but no easy numbering method? So: how to insert a numbered equation in Word 2007 and reference it in the text. For the first part, I follow this blog post. 1. Insert a 3 column, 1 row table. 2. Format the table to fill 100% of the page width, with the column widths in percent as 15:70:15. 3. Centre the text in the middle column and remove all table borders. Make the spacing below the table the same as other paragraphs. 4. Insert your equation in the middle column. (I use insert>object>M$ equation 3.0 since the new equation package won't work on my machine).
5. Insert a number in the right-hand column by insert>multilevel list. You can define your own so that the numbers are formatted like (x).

Here is the nice part (ha ha). Since my "equation gallery" is broken too, I can't save these shenanigans for easy re-use. To insert a new equation later, I simply copy the whole table and paste it elsewhere and change the equation! The numbers automatically sort themselves out (hallelujah).

To reference the numbered equation in the text:

1. Highlight the equation number and insert>bookmark. Give it a nice name.
2. Put the cursor at the place where you want your reference inserted and insert>cross-reference. Insert a reference of type "bookmark", select the name of your equation and insert the reference to the paragraph number (full context).

There. That was a complete pain, wasn't it? And it took about 40 mouse-clicks! Doesn't your equation look horridly rendered too? Oh, I love LaTeX and I want it back.

### Save excel graphs as vector images

This is a lame workaround to get excel plots as vector images.

Select your Micro$oft Excel plots. Copy. Open Micro$oft PowerPoint. Paste-special as enhanced metafile (emf) into an otherwise empty slide. Save your PowerPoint slide as an "other format" file (on the 2007 menu), and choose "emf" (an enhanced windows metafile! wow!). Import your emf file into inkscape and ungroup the object. Delect all the a4-sized crappy blank space from the image and enjoy.

### Excel axis labels workaround

Problem:
When making an x-y scatter plot in Micro\$oft Excel 2007, there appears to be a bug which prevents the x-axis tick labels displaying correctly (at least on my machine). When you set the x-axis tick labels to text, e.g. "apple", "banana", "pear"..., the chart just displays the labels as 1, 2, 3... even when you are careful to select the cells containing the text labels as your x-data, and despite them showing up correctly in the "select data" dialogue box. This only appears to be an issue for the x-y scatter plot type.

Workaround 1:
Install linux boot disc...

Workaround 2:
Add a new dummy data series to your graph with x = {"apple", "banana", "pear"...} and y = {0, 0, 0...}, or some other value below the y-axis minimum. Select only this series, and set the chart type to area. The x-axis tick labels should now display correctly for the whole chart. Obviously delete the dummy data label from your legend, if you have one.

### Stupid papersize stupid stupid

After finally getting to the stage where my thesis would compile on a different computer (see last post to install the extra .sty files), I then discover my page headers have disappeared on my pdf output. It turns out that this is due to the default ps2pdf setting being US letter paper, rather than the A4 size that the rest of my document is on. The answer (for the moment, anyway) is this:
ps2pdf -sPAPERSIZE=a4 thesis.ps
I'm forced to go a-latexin' followed by dvipsin' then ps2pdf because of some bounding box issues with my images with pdflatex that I can't be bothered to solve.
That will serve me right for having a typo in my thesis.

### Installing a latex .sty file

I've never managed to successfully do this until now. Here's the deal:
1) download & unzip the package from CTAN
2) run latex on the .ins file so that it creates a .sty file
3) find out what your computer thinks your TDS tree should be:
kpsewhich -var-value TEXMFLOCAL
(mine says "/usr/local/share/texmf")
4) create the tree /usr/local/share/texmf/tex/latex/ if it isn't already there (where is the name of your sty file)
5) paste in your .sty file
6) run mktexlsr /usr/local/share/texmf/
7) profit.

### Including pdf files into latex

Further to my earlier post today, this post is the story of how I managed to get my research papers into my thesis as appendices. The earlier post tells a fascinating tale of how I sorted the page counters out and forced some blank pages. I then compiled up to pdf (via ps2pdf, to include my eps diagrams). To insert my other pdf pages I wrote a new latex file to stitch stuff together using pdfpages. Sadly this makes my hyperlinks go away, but nevermind. The object here is to be able to have a file which can be printed and bound by people who don't care to re-arrange pages for me. Behold:

\documentclass[a4paper,portrait]{article}
\usepackage{pdfpages}

\begin{document}

\includepdf[pages={1-32}]{thesis.pdf}
\includepdf[pages={33-34}, landscape, turn=false]{thesis.pdf} % some landscape pages
\includepdf[pages={35-202}]{thesis.pdf}
\includepdf[pages={1-5,{},{},{}}, landscape, nup=1x2, turn=false]{Appendices/specs.pdf}
\includepdf[pages={203-204}]{thesis.pdf}
\includepdf[pages={1-4}]{Appendices/prl.pdf}
\includepdf[pages={205-206}]{thesis.pdf}
\includepdf[pages={1-4}]{Appendices/pra.pdf}
\includepdf[pages={207-220}]{thesis.pdf}

\end{document}

Chunks of my thesis are included (I guess you can spot them), including some landscape pages as a special case. The "turn = false" means that any pdf viewers still display them as portrait. This was important to me, as I want to be able to check they're not going to print upside down! The last two appendices are four pages each and on American letter ("freedom") paper, but that's okay: they'll be scaled for A4. The "specs.pdf" file is 5 pages long and I have included it as 2-up printing on landscape pages which show as portrait in the viewer. Since I needed ensure that they occupy 4 sides of A4 in total, I included 3 blank pages denoted by the empty braces {}. So, the first two-and-a-half sides of A4 have the 5 pages of specs.pdf, and then there are one-and-a-half blank sides following.

I compile with pdflatex.

### LaTeX: coloured text and blank page fun.

I want to insert some research papers into my thesis. These are in separate pdf files which I don't yet know how I will insert. (pdfpages isn't my friend because I'm banned from using pdflatex due to having eps graphics which I can't be bothered to convert.)

I'll figure out that bit in a minute, but right now I want to force a blank page (with a header and footer) which will be printed on the reverse of an appendix section page. This has to come before the place where I will insert the pdf pages. Actually, latex adds this page automatically at the moment, because it wants my "Appendix" section pages to be on the right-hand sides of my document. The issue is that if I then start to add to my page counter, the reverse-side blank page has the wrong page number for where it will be printed!

Here's my work-around. Each introductory page for an appendix goes like this:

\chapter{An included paper}
Following is a copy of an amazing paper from our research group.
\newpage
\mbox{}

The mbox ensures the new page actually happens. Then, before the next \include{} in the master file, I add four pages (the research paper length!) to my counter.

So far, so awesome. Now I'll fight to include the papers in the file. I'm thinking psutils...

OH! I forgot to tell you about coloured text! Before I found the mbox doo-dah I was going to just write "cheese" in white on the blank page. I'd do the following in my preamble:

\usepackage{color}
\definecolor{orange}{rgb}{1,0.5,0}

and then on my "blank" page, I'd do:

\newpage
\textcolor{orange}{cheese}

Ok, that's orange, but you get the picture. You can define white.

### Non-coloured hyperrefs in latex

So, I love to leap around my thesis like superman using the "hyperref" package. However, I do not like increased printing costs by having pretty pink references on every page (our printer selects the cheaper b/w printing intelligently). I was colouring my links black using this clunky bit of code:
\hypersetup{
citecolor=black,%
filecolor=black,%
urlcolor=black
}
...but this resulted in the printer choosing to mix colours to achieve black text on pages with a hyperlink! Argh! It looked stupid, it was stupid! Hopefully this more elegant bit of code might fix whatever oddity is occuring:
\hypersetup{pdfborder={0 0 0},colorlinks = false}
The pdf certainly looks no different... fingers crossed for printing time.

### Sidewaystable prints upside down

I have two consecutive landscape tables in my thesis using the "sidewaystable" package. The package rotates them so that the top of the table is closest to the spine of the book, however this manifests itself in the pdf as the page headers and footers appearing to the right of one landscape page, and to the left of the next. When I print double sided, one page has a header which is upside down. My preamble is thusly:

\documentclass[a4paper,11pt,twoside]{book}
\usepackage{rotating}

... the solution was to choose:

\usepackage[figuresright]{rotating}

So that the figures are always in one direction. Now my headers are always to the right of the landscape page. Hopefully this will now force them to be the right-way-up! If they both print upside down, I suppose I must choose [figuresleft] instead. I've no idea if this is just a symptom of my particular combination of pdf reader and printer, but hey-ho.

Thanks to the Szwer for solving this one for me.

### Breaking URLs in BibTeX

Here's a work-around for a sticky problem when citing URLs in LaTeX documents.

My problem manifested itself in ugly URLs in my bibliography which did not break over multiple lines, causing underfull hboxes all over the shop: the line of text preceding the URLs had 5 words spread horridly across the page.

I tried various work-arounds found via google but the one that eventually solved my problem was found here in "BibTeX tips and FAQ" by M. Shell and D. Hoadley.

My preamble contains the following:
\usepackage{url}
\usepackage[ps2pdf, pagebackref]{hyperref}

And I cite all my URLs in BibTeX like this:
\url{http://morecakelessfish.blogspot.com/}

I like to compile into pdf by using dvi2ps then ps2pdf otherwise I seem to have some issues with offset bounding boxes in my pyxplot .eps graphics. Despite calling the url package in my references (see example above), my URLs still weren't breaking. Apparently this is a problem when going via dvi after including the hyperref package. The problem was solved by including breakurl.sty AFTER the hyperref package in my preamble thusly:

\usepackage{url}
\usepackage[ps2pdf, pagebackref]{hyperref}
\usepackage{breakurl}

Jobs a good'un.
