%-----------------------------------------------------------
% When including a figure in your poster, be sure that the commands are typed in the following order:
% \Begin{figure}
% \includegraphics[...]{...}
% \caption{...}
% \End{figure}
% That is, put the \caption after the \includegraphics

\Begin{alertblock}{Summary}
Here is a barebones document for an A0 poster.
It was based off http://www.nathanieljohnston.com/2009/08/latex-poster-template/ but has been modified to work as an R Markdown file to be compiled with knitr (rmd to md) and then pandoc (md to tex) and then latex (tex to pdf).

Alert blocks are shaded and have padding so use them for the conclusion/summary.
\End{alertblock}
<!--  --------------------- -->
\Begin{block}{The Setup}
Required files:

* `poster.md`, this example R Markdown file.
* `poster-pandoc-template.tex`, the pandoc template for the poster.
* `beamerthemeconfposter.sty`, the beamer style file (I **think** you may be able to substitute your own, but I used the one from [here (
Computational Physics and Biophysics Group, Jacobs University, with modification by Nathaniel Johnston and Vel Gayevskiy)](https://www.overleaf.com/latex/templates/landscape-beamer-poster-template/vjpmsxxdvtqk)
     
Also: 

* LaTeX packages `latexbeamer`, `pgf` (Tikz), `beamerposter`
* R package `knitr`
* pandoc

I've only tested this compiling from Rstudio.
  You can set authors and affiliations in the YAML metadata, along with limited beamer styling (block rounded corners and so on).
  
\Begin{subblock}{Subblocks}
These are essentially second-level headings. The environment is called `subblock`.
The font size is slightly smaller. Set the heading colour via **TODO**.

**TODO**: the spacing seems to have disappeared again.
\End{subblock}
\End{block}
\End{column}
<!--  --------------------- -->
<!-- Second column. spanning two columns -->
<!--  --------------------- -->
<!-- column spanning two columns. -->
\Begin{column}{2\colwid}
\Begin{block}{Altering Column Spans}
You can make columns that span multiple other columns relatively easily. Lengths are defined in the template that make columns look normal-ish if you want to use a three-column layout like this poster. If you want to use a different number of columns, you can specify the base column width in the YAML preamble.

In particular, in the YAML:

~~~
  columnwidth: '0.3\paperwidth'
~~~
      
You get `\colwid` for free, and using the `calc` package you can get multiples of it.
\End{block}
<!--  --------------------- -->
<!-- split up the 2-col wide column --> 
<!--  --------------------- -->
\nopandoc{\Begin{columns}[t,totalwidth=2\colwid]}
<!--  --------------------- -->
<!-- Second column -->
<!--  --------------------- -->
\Begin{column}{\colwid}
\Begin{block}{Block Colours}
For the standard blocks there are two colours; one for the title and one for the block body:

      \setbeamercolor{block title}{fg=red,bg=white}
      \setbeamercolor{block  body}{fg=black,bg=white}

The `fg` colour sets the text colour and `bg` sets the background colour.
For the normal blocks it makes no sense to use a background colour other than white. You *can* change it, but it will look weird!
\End{block}<!-- Block colours -->
<!--  --------------------- -->
\Begin{block}{Todo}

* verbatim straight quotes.
* knitr...
* bibliography
* theming: user puts in a theme e.g. warsaw first for colours if they like
* more control over font size
* spacing between institutions seems too large
* logos
* bibliography without explicit `\bibitem`, ie integrate biblatex?
* more spacing between blocks//standard spacing
* easy styling and so on.
* [WONT] explicit control over separator width?
