# New with shiny!

## Automated testing

  - `devtools::install_github("rstudio/shinytest")` To install the package from the github repo

  - `shinytest::recordTest()` To create a baseline

  - `shinytest::testApp()` To test the app after some package versions have been updated

  - `shinytest::snapshotupdate()` To update the snapshot taken during the recordTest


## Web Apps vs. Web APIs

  - Shiny does not work great for Web APIs

  - By using `session$api$data <- serveCSV(...)` with `/api/data`, you can access to data available through the API


# Whats new with the IDE?

## Some shortcuts

  - `Ctrl` + `Shift` + up to increase size of selection

  - `Ctrl` + `Shift` + down to reduce size of selection

  - Rename variable in scope

  - Automatic insertion of Roxygnen skeleton

  - `Ctrl` + `Shift` + a to re/format code

  - `Ctrl` + `Alt` + click to get a larger cursor

  - `Alt` + click to draw a cursor

  - `Ctrl` + dot "." to find an object within the project

  - `Alt` + `Shift` + K to all shortcuts

# Shiny dashboards

## `shinydhasboards` package, more of this in the dashboards directory with live code examples

## `flexdashboard` package

  - `valueBox()` Function to create value boxes

  - `gauge()` Function to create gauges

  -

## Dashboards + Shiny!

  - Can include shiny commands and functions, without having a ui - server logic

  - can generate the rmd with a uiOutput

  - `runtime: shiny_prerendered`


```{r, eval = F}

ui <- uiOutput("contents")

server <-
  ...{
    output$contents <- renderUI({
      rmarkdown::render("source.Rmd")
    })
  }


```

# Websites with Rmd

## `blogdown` package

  - `devtools::install_github("rstudio/blogdown")` To install the package from github

  - `blogdown::new_site()` To install `Hugo`, and create a preview of a website

  - Embedded code, text output, graphics output supported, just like normal Rmd

  - The viewer listens to the document, no need to re-render the documents

  - Themes from Hugo can be used

  - `blogdown::new_post()` Creates the YAML metadata needed, and builds a new post under a new directory

  - From a normal Rmarkdown, one can use `output format: blogdown::html_page` to produce blogdowns


# Other Rmd talks

## Talk 1

###`rticles` package

  - [GitHub Repository](https://www.github.com/rstudio/rticles)

  - LaTeX templates for Pandoc


### `tufte` package

  - tufte allows a main column for the body and a smaller side column for figs, side notes, or any other stuff

  - This package has the `full.width = TRUE` option in the code chunks

  - Package created in a responsive environment. Si denotes become hidden in smaller screens, and can be accessed by clicking on body text that references them.

### `xaringan` package

  - Allows a more friendly interface for html output and presentation

  - slides in presentation mode

  - Output formats for \*.pdf, \*.html, and e-books

  - https://bookdown.org/yihui/bookdown/

  - Cross-referenced figures supported


## Talk 2

### Customize Rmd

  - First, check existing options in the Rmd page

  - Rmarkdown calls Knitr, which translates everything into Markdown, and then calls pandoc, which translates everything into the desired output
