How to make an interactive isoslides presentation using Shiny and Rmarkdown?

When I make a Shiny app in an .Rmd file to make an isoslides presentation, the app "behaves" like a static html page (interactivity is not possible).

For example, the following code in an Rmd file will produce a static html presentation that you can not interactively use.

---
output: ioslides_presentation
---

## Useless App

```{r echo=FALSE, message=FALSE, warning=FALSE}
library(shiny)

ui = fluidPage(
        numericInput("n", "How old are you?", value = 1)
)

server = function(input, output, session) {
        
}

shinyApp(ui, server)

What am I missing?

You can't do this unfortunately.

The closest thing would be to deploy your shiny app to some address, either on the web or local, and then embed it in your slides with an iframe.

For example:

---
output: ioslides_presentation
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

## Slide with plot

```{r}
plot(cars)
```

## Slide with Shiny app in iframe

<iframe width = "560" height = "315" src="https://nsgrantham.shinyapps.io/tidytuesdayrocks/"></iframe>

enter image description here

If you wanted to do this with a local app, you would deploy your app in a separate R session, then grab the local address from the browser (e.g. something like: http://111.0.0.1:1234/ and paste that as the iframe source.

The above answer is inaccurate.

For your YAML header

---
output: ioslides_presentation
runtime: shiny
---

To embed your shiny app (assuming it is a separate file):

```{r, echo = FALSE, message=F, warning=FALSE}
shinyAppFile(
  "FileMyAppIsIn/app.R",
  options = list(width = "100%", height = 700)
)
