Creating Your First App

A basic Shiny app requires:

• UI function to define the layout
• Server function to handle logic
• shinyApp() to combine both

Tip: Use shinyApp() for simple apps or create separate ui.R and server.R files for larger projects.

For inline code, use backticks like runApp() to execute your application.
