This example uses both ggplot and plotly syntax to create the shiny app. Grab the scripts here or a simpler version here! server.R contains the graph, written in Plotly syntax and ui.R consists of a title panel, a sidebar panel with the slider to select the number of bins, and a main panel that displays the graph. This simple example (based on Hello Shiny) uses Plotly syntax to create a histogram of movie ratings (from a ggplot/plotly built in data set) where the user can change the number of bins in the histogram. After publishing the app, it’s quite easy to embed the app in a website!Īlternatively, it’s possible to run the app by setting the working directory to the directory that contains the app folder and then run library(shiny) and runApp("My_App").
Once all of the components are stored in a folder just open the runApp.R in RStudio and select “Run App” or, if you have a Shiny Apps account, you can log in then select Publish. The plotlyGraphWidget.js script should be inside a folder named www inside the app folder: (1) global.R (2) plotlyGraphWidget.R and (3) plotlyGraphWidget.js are all available here! There’s also an optional runApp script that installs the necessary packages and makes it easy to run the app (see instructions below). To make a shiny app that is a plotly widget, just add 3 scripts to your app folder in addition to the ui.R and server.R. In other words, the ui script creates what the user sees and controls and the server script completes calculations and creates the plots. The user interface script controls the layout of the app and the server script controls what the app does. Shiny apps involve two main components: a ui (user interface) script and a server script. That means your team can create graphs in Shiny, then export and share them. Shiny is an R package that allows users to build interactive web applications easily in R! Using Shiny and Plotly together, you can deploy an interactive dashboard. Read the new Plotly-Shiny client tutorial. The Plotly-Shiny client has been updated with the 2.0 R client release.
