R Language Shiny Create an app
Example
Shiny is an R package developed by RStudio that allows the creation of web pages to interactively display the results of an analysis in R.
There are two simple ways to create a Shiny app:
- in one
.Rfile, or - in two files:
ui.Randserver.R.
A Shiny app is divided into two parts:
- ui: A user interface script, controlling the layout and appearance of the application.
- server: A server script which contains code to allow the application to react.
One file
library(shiny)
# Create the UI
ui <- shinyUI(fluidPage(
# Application title
titlePanel("Hello World!")
))
# Create the server function
server <- shinyServer(function(input, output){})
# Run the app
shinyApp(ui = ui, server = server)
Two files
Create ui.R file
library(shiny)
# Define UI for application
shinyUI(fluidPage(
# Application title
titlePanel("Hello World!")
))
Create server.R file
library(shiny)
# Define server logic
shinyServer(function(input, output){})
