Welcome to the {iheiddown} twist of the great {posterdown} poster template ! This poster, alongside their #betterposter versions, allow students and researchers to create IHEID-themed posters easily within R. The remaining part of this template allows you to get familiar with its layout. Head over to {posterdown} if you fancy having a look at the original version!


  1. Easy to use reproducible poster design.
  2. Integration with R Markdown.
  3. Easy transition from {iheiddown} to {pagedown} report or manuscript documents (Xie et al. 2022).


This package uses the same workflow approach as the R Markdown you know and love. Basically it goes from RMarkdown > Knitr > Markdown > Pandoc > HTML/CSS > PDF. You can even use the bibliography the same way (???).


Usually you want to have a nice table displaying some important results that you have calculated. In {iheiddown} this is as easy as using the {kable} table formatting you are probably use to as per typical R Markdown formatting.

You can reference tables like so: Table 1. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam placerat augue at velit tincidunt semper. Donec elementum porta posuere. Nullam interdum, odio at tincidunt feugiat, turpis nisi blandit eros, eu posuere risus felis non quam. Nam eget lorem odio. Duis et aliquet orci. Phasellus nec viverra est.

Table 1: Table caption.
Sepal.Length Sepal.Width Petal.Length Petal.Width
5.1 3.5 1.4 0.2
4.9 3.0 1.4 0.2
4.7 3.2 1.3 0.2
4.6 3.1 1.5 0.2
5.0 3.6 1.4 0.2
5.4 3.9 1.7 0.4
4.6 3.4 1.4 0.3
5.0 3.4 1.5 0.2
4.4 2.9 1.4 0.2
4.9 3.1 1.5 0.1

Or with figures: Figure 1, or Figure 2.

Great figure!

Figure 1: Great figure!

data <- iris

plot(x = data$Sepal.Length, 
     y = data$Sepal.Width, 
     col = data$Species,
     pch = 19, 
     xlab = "Sepal Length (cm)",
     ylab = "Sepal Width (cm)")
Amazing, right?!

Figure 2: Amazing, right?!
