How can I create interactive web applications using R Shiny?

To create interactive web applications with R Shiny, you need to install the Shiny package and set up a basic app structure.

What are the key components of a Shiny app?

A Shiny app typically consists of a UI (user interface) and a server function. The UI defines how the app looks, while the server handles the logic.

Can you show me a simple example of a Shiny app?

Sure! Here's a basic example:

library(shiny)

ui <- fluidPage(
  titlePanel("Hello Shiny!"),
  sidebarLayout(
    sidebarPanel(
      sliderInput("obs", "Number of observations:", 1, 100, 50)
    ),
    mainPanel(
      plotOutput("distPlot")
    )
  )
)

server <- function(input, output) {
  output$distPlot <- renderPlot({
    hist(rnorm(input$obs))
  })
}

shinyApp(ui = ui, server = server)

How do I deploy my Shiny app online?

You can deploy your Shiny app online using services like shinyapps.io or by hosting it on your own server with Shiny Server.
