An example of a shinydashboard. See that there are many interactive elements that we can place in there.

An example of a shiny app from Rstudio

A shiny app is like a restaurant
A user of the shinyApp is like a patron
A user interface contains outputs and inputs
- The output is like the dishes
- The input is like the order
The waiter passes down the order to the kitchen and brings the food to us
- The server tells the app what output to produce based on the user input

A user of the shinyApp is like a patron of a restaurant.

The waiter passes down the order to the kitchen and brings the food to us.

library(shiny)

ui <- fluidPage(titlePanel("Your first app"))

server <- function(input, output){
}

shinyApp(ui, server)

The shinyApp that is rendered from the code in the previous slide. See that it is an empty app with no inputs or outputs.
