posterdown

As a graduate student, I found that it is almost a rite of passage to take early research and analysis and generate a conference poster allowing for critical feedback as well as meeting the people in your field. I have also noticed that many of my fellow graduate students use R and are also getting their feet wet with RMarkdown :blush:; however, we always had to go back to using MS Powerpoint or Keynote for generating conference posters :unamused:. Posterdown was created as a proof of concept (to myself) that it is possible to make a beautiful poster using open source reproducible code.

Please feel free to give me feedback or requests for changes in the issues page. I am currently finishing up my masters so I will have limitted time to work on updating this package in the next few months but nevertheless I will do what I can! :smile:

Installation

You can install and use posterdown from github using the devtools package as seen below.


devtools::install_github("brentthorne/posterdown")

Instructions if you have never used RMarkdown

Install devtools package
```
install.packages("devtools")
```

Install posterdown from github repo

devtools::install_github("brentthorne/posterdown")

Install tinytexLatex libraries:
```
tinytex::install_tinytex()
```
NOTE This will take some time to load the LaTex Packages but is the best options in my opinion for keeping your Latex library as small as possible. After the first download of these libraries you will not need to do this again. To confirm that Tinytex is properly installed use: tinytexy:::is_tinytex() and you should get a value of TRUE in the console.

Overview

The posterdown package provides a familiar workflow for those used to working in RMarkdown. This package is currently focused on a single template called posterdown_pdf which is by default a 38in (H) x 45in (W) poster template but does allow for custom sizing, section headers, and colour options.

Using posterdown from RStudio

To use posterdown from RStudio:

Install the latest RStudio.

Install the posterdown package:

devtools::install_github("brentthorne/posterdown")

Use the New R Markdown dialog to create a conference poster from the templates
NOTE If you do not see the posterdown template in this dialogue box try to restart the R session or close and re-open RStudio.

Customization

Posterdown uses Latex to generate the PDF poster but more specifically it uses the Memoir Latex class. Memoir was chosen for its flexability in page sizing as well as thorough documentation. I am fairly new to the world of Latex and found this class to have a reasonable amount of customization available, at least for my skill level. If there are any users who think there may be better options for down the road I am more than willing to listen!

YAML OPTIONS

YAML header options have been created to privide more freedom with design (ie colours, number of columns, and sizing) to fit a wide variety of requirments. Here are the default YAML options found in the .Rmd file:

Option	Description
`title`	Poster title, acts as you would expect from RMarkdown.
`author`	List of authors which (as of now) only has true support for a single author, however I have provided a hacky way to have many authors until I can find the time to figure out how to impliment something like the rticles packages does
`affiliation`	Author affiliations, which just as the `author` section is currently a hacky version of what I would ultimately like to produce.
`font_size`	Represents the value for `\normaltextsize` in latex. All other font sizes are adjusted around this, for example, the title in the skeleton document is given the Latex command `\Huge`, meaning that the title text will be "huge" relative to the `font_size` chosen. Here is a usefull resource for better understanding the Latex text sizing options.
`font_family`	Selects the font family to be used on the poster, in the future I will try to mipiment multiple font families for various components of the poster (such as different fonts for the title versus the main body text). For now only standard Latex fonts are availble, see here for a list of possible options.
`title_bgcol`	The background colour for the title section of the poster (currently using hex values to define this colour)
`poster_bgcol`	Background colour of the posters main body section.
`title_textcol`	Colour of the main title text.
`header_textcol`	Colour of the Section Header Text
`cite_col`	Colour of the citation link elements when using `biblatex`.
`url_col`	Colour of URL links specifically
`link_col`	Colour of in document links (example would be referencing a Figure or a Table)
`columnline_col`	Colour of the line which divides each column in the poster
`poster_height`	Height of the final poster output. Units can be: "in", "mm", "cm"
`poster_width`	Width of the final poster output. Units can be: "in", "mm", "cm"
`column_numbers`	Number of columns you wish for the poster to have in the main section of the poster.
`bibliography`	Name of the `.bib`. file which you are using to source material. As of right now only `biblatex` is working but I intend to add support of `natbib` which is my preference.
`output`	For generating `posterdown_pdf`, in the future other poster designs or templates may be made for this package and thus this option in the YAML will be more flexible. For now this is the only option.

Markdown Customization

As you add content to your RMarkdown file you will notice the output pdf will fill in columns from left to right as well as top to bottom. If you have more content to fit than what is available on the default poster try altering the number of columns as well as the font size to make it work.

Using posterdown outside of RStudio

Install pandoc using the instructions for your platform.

Install the rmarkdown and posterdown packages:

devtools::install_github("brentthorne/posterdown")

Use the rmarkdown::draft() function to create articles:

rmarkdown::draft("MyPoster.Rmd", template = "posterdown_pdf", package = "posterdown")

TODO
