 # Introduction
 
 This is the `posterdown_betterland` 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 [@thorneposterdown2019]. 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 :)
-
-# Methods
-
-1. Install R and `posterdown`, see [github](github.com/brentthorne/posterdown)
-2. Open the `posterdown_betterland` template
-3. Make all your poster dreams come true!
-
-# Results
-
-```{r, out.width='90%', fig.height=5.5, fig.cap='Using {ggplot} and {patchwork} to generate a layout of multiple plots in one figure [@patchwork2017].'}
-
-library(tidyverse)
-library(patchwork)
-library(ggthemes)
-
-theme_set(theme_tufte() + theme(legend.position = "none"))
-
-base <- ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, colour = Species))
-  
-p_point <- base + geom_point()
-p_line  <- base + geom_line() 
-p_area  <- base + geom_area()
-p_box1  <- ggplot(iris) + geom_boxplot(aes(x = Species, y = Sepal.Length, fill = Species))
-p_box2  <- ggplot(iris) + geom_boxplot(aes(x = Species, y = Sepal.Width, fill = Species))
-
-p_line +

-## More Figures and Tables
-
-```{r, mytable, fig.align='center', out.width='90%'}
-
-library(knitr)
-library(kableExtra)

-  kable_styling(full_width = T) %>% 
-  row_spec(0, color = "#fff", background = "#0b454580")
-```
-
-```{r, echo=TRUE}
-library(ggplot2)
-library(ggspatial)
-
-load_longlake_data()
-
-map <- ggplot() + 
-  theme_pander() +
-  layer_spatial(longlake_depthdf,
-                aes(colour = DEPTH)) +
-  theme(legend.position = "bottom")
-```
-
-```{r, mymapfig, out.width='70%', cache=FALSE, fig.cap='Map of Long Lake eample from the [ggspatial](https://github.com/paleolimbot/ggspatial) package [@ggspatial].',strip.white= TRUE, comment=FALSE}
-
-ggsave(map,filename = "Figures/map.svg", width = 3.5, height = 3.5, device = 'svg', bg = 'transparent')
-
-knitr::include_graphics("Figures/map.svg")
-```

-A **BIG** thank you to [Romain Leasur](https://twitter.com/RLesur) and [Yihui Xie](https://twitter.com/xieyihui) for their wonderful work on [{pagedown}](https://github.com/rstudio/pagedown) which had made this poster possible [@pagedown]!
