I am working with posterdown to make a poster in portrait orientation. But, I have trying with this for a while and I need help with it.
First. I would like to increase the size of one of the logos that I have added, I have tried in several ways that I found and It does not work.
I would like to reduce the blue bar in the top because it is so large. Finally, I would like to include more logos not only three, how to do this?
The code that I consider is the next one:
---
main_topsize: 0.2 #percent coverage of the poster
main_bottomsize: 0.1

# Introduction
This is the `posterdown_betterport` template for the {posterdown} package! I was inspired by the twitter thread of [Mike Morrison](https://mobile.twitter.com/mikemorrison/status/1110191245035479041) and wanted to apply the `#betterposter` concept to the reproducible (yet simple to use) functionality of the {posterdown} package [@R-posterdown]. If you're not an R user don't sweat as you do **NOT** need to use it at all! Feel free to use only the Markdown functionality of this package :)
```{r, include=FALSE}
knitr::write_bib(c('posterdown', 'rmarkdown','pagedown'), 'packages.bib')
```
## Objectives
1. Pick a template layout.
2. Write/ create your poster content distraction free.
3. Let posterdown do its thing!
# Methods
I will show here how to include poster elements that may be useful, such as an equation using mathjax:
$$
E = mc^2
$$
To reference a citation you can add your `.bib` file to the working directory and name it in the YAML metadata or generate an automated one as done here, then you only need to reference the label value in the `.bib` file. For example this package is built on top of the wonderful {pagedown} package and I will cite it at the end of this sentance using this in the rmd `[@R-pagedown]` [@R-pagedown].
To get a better understanding of how to include features like these please refer to the {posterdown} [wiki](https://github.com/posterdown/wiki).
**_Now on to the results!_**
# Results
Here you may have some figures to show off, bellow I have made a scatterplot with the infamous Iris dataset and I can even reference to the figure automatically like this, `Figure \@ref(fig:irisfigure)`, Figure \@ref(fig:irisfigure).
```{r, irisfigure, fig.cap='Here is a caption for the figure. This can be added by using the "fig.cap" option in the r code chunk options, see this [link](https://yihui.name/knitr/options/#plots) from the legend himself, [Yihui Xie](https://twitter.com/xieyihui).', out.width="80%"}
par(mar=c(2,2,0,1))
plot(x = iris$Sepal.Length, y = iris$Sepal.Width,
col = iris$Species, pch = 19, xlab = "Sepal Length",
ylab = "Sepal Width")
```
Maybe you want to show off some of that fancy code you spent so much time on to make that figure, well you can do that too! Just use the `echo=TRUE` option in the r code chunk options, Figure \@ref(fig:myprettycode)!
```{r myprettycode, echo=TRUE, fig.cap='Boxplots, so hot right now!', fig.height=6, out.width="80%"}
#trim whitespace
par(mar=c(2,2,0,0))
#plot boxplots
boxplot(iris$Sepal.Width~iris$Species,
col = "#008080",
border = "#0b4545",
ylab = "Sepal Width (cm)",
xlab = "Species")
```
How about a neat table of data? See, Table \@ref(tab:iristable):
```{r, iristable}
knitr::kable(
iris[1:15,1:5], format = "html",
caption = "A table made with the **knitr::kable** function.",
align = "c", col.names = c("Sepal <br> Length",
"Sepal <br> Width",
"Petal <br> Length",
"Petal <br> Width",
"Species"),
escape = FALSE)
```
# References
I found in the manual of this library that there is an option logoleft_width:.... but it is not clear about the units. As you can see, I have selected
logoleft_width: "15cm"
but after running the code the size of the logo never changes.
The same with the font size I have tried
font_size: 32
and I have changed to other values, but the size does not change.
Another question that is not clear to me is:
logoleft_name: https://raw.githubusercontent.com/brentthorne/posterdown/master/images/betterhexlogo.png
Here the questions is: If I want to put an image that is in my computer how to do that? because I have been trying writing the directory but it does not works. I dont know if I need to include an specific sintaxis. Moreover how to include more logos but in the top not in the bottom?
The link of the output of the code is in:
