Shiny is an R package that allows you to build interactive web applications directly from R. These applications can range from simple data visualizations to complex data analysis tools. Shiny leverages R’s strengths in statistical computing and data analysis and provides a framework for creating web applications with minimal HTML, CSS, and JavaScript knowledge. Below is a deep dive into building Shiny apps:

1. Install and Load Shiny:

install.packages("shiny")
library(shiny)

2. Basic Structure:

A Shiny app consists of two main parts: the user interface (UI) and the server.

a. UI Function:

• Defines the layout and appearance of the app.

ui <- fluidPage(
  # UI components go here
)

b. Server Function:

Contains the logic and processing for the app.

server <- function(input, output) {
  # Server logic goes here
}

3. UI Components:

a. Layout Functions:

• fluidPage, navbarPage, dashboardPage, etc.

b. UI Components:
