In today's data-driven world, the ability to transform raw data into actionable insights is crucial for businesses, academics, and policymakers. Shiny, an R package, is at the forefront of this transformation, enabling users to build interactive web applications with ease. This blog explores what Shiny is, how it works, and its applications in the real world.

What is Shiny and How It Works

Shiny is an open-source R package that allows users to create interactive web applications directly from R, a language and environment for statistical computing. By combining the power of R with the interactivity of web development, Shiny enables users to build applications that can host complex data visualizations, perform real-time calculations, and provide an engaging user experience.

Shiny applications are composed of two main components: the UI (User Interface) and the Server. The UI defines the layout and appearance of the application, while the Server handles the application's functionality and logic. Users can utilize HTML, CSS, and JavaScript to enhance their applications, making Shiny a versatile tool for data scientists and developers alike.

How Shiny Work

Creating Interactive Apps for Data-Driven Decisions

The true power of Shiny lies in its ability to create interactive applications tailored to data-driven decision-making. By enabling users to manipulate data through dynamic inputs such as sliders, dropdowns, and text fields, Shiny apps allow for real-time analysis and visualization, encouraging informed decision-making.

For instance, a company could use a Shiny app to visualize sales data, allowing managers to adjust variables like time frames and product categories to identify trends. Similarly, academics can harness Shiny to create tools for exploring complex datasets, facilitating greater understanding and discovery in research.

Embedding Dashboards in Business or Academic Projects

One of Shiny’s significant advantages is its ability to embed dashboards in various projects, providing a seamless way to share insights. Whether in a business context, where dashboards can be embedded into company intranets, or in academia, where they can be incorporated into online courses and research papers, Shiny applications offer versatile integration options.

By sharing Shiny dashboards, stakeholders can access up-to-date information, enabling collaboration and fostering a data-driven culture. Furthermore, the open-source nature of Shiny encourages customization and the development of bespoke solutions tailored to specific organizational needs.

Real-World Hook: Shiny Dashboards in Action

Shiny dashboards have found applications across numerous fields, including healthcare, policy analytics, and business reporting.

Healthcare: Hospitals utilize Shiny dashboards to monitor patient data in real-time, helping medical professionals make informed decisions quickly. For instance, dashboards can track patient vitals, medication schedules, and bed occupancy rates, optimizing hospital operations and improving patient outcomes.

Policy Analytics: Policymakers use Shiny to analyze data related to social issues, enabling them to model the potential impact of different policy decisions. By visualizing data effectively, policymakers can communicate findings to stakeholders and the public, facilitating transparency and informed decision-making.

Business Reporting: Companies implement Shiny dashboards to report on key performance indicators (KPIs), allowing executives to drill down into data for in-depth analysis. These dashboards can be customized to reflect organizational goals, providing a clear picture of business performance.

The biggest liars in US politics

by Thomas L Vincent

Most Americans, and anyone that follows US politics, will be aware of the tremendous changes and volatility that has struck the US political landscape in the past year. The ascent of Donald Trump from a billionaire entertainer to a fully fledged presidential candidate, alongside the unexpected popularity of Bernie Sanders and the nomination of Hillary Clinton as the first female presidential candidate, has catapulted this political season into one of the most entertaining, vicious and confusing year.

Great tutorial from #useR2016: “Effective Shiny Programming” by @jcheng

Effective Shiny Programming

Joe Cheng, RStudio, Inc.

Tutorial Description

Shiny is a package for R that makes it easy to build interactive applications that combine the friendliness of a web page with the power of R. The goal of this tutorial is to help Shiny app authors to improve their Shiny skills, so that they can build apps that are easier to write, debug, and enhance.

Tutorial Outline

Reactive programming: Gain a deeper understanding of Shiny's reactive programming paradigm, which is essential for building robust, efficient apps.

Bookmarkable state and database integration: Get a preview of these major new features from the next release of Shiny.

Tips and tricks: Learn about handy features like req(), cancelOutput(), and reactivePoll(), and how they can help you write more sophisticated apps.

Background Knowledge

This tutorial is intended for R users who already have experience building Shiny apps and are looking to dive deeper. Attendees are expected to have completed the online tutorial at http://shiny.rstudio.com, and to have created one or two original apps. Much of the material is in the form of hands-on exercises, so attendees will be expected to bring their own laptop.

Instructor Biography

Joe Cheng is the CTO of RStudio, Inc. He is the creator of Shiny, and several other R packages including htmltools, httpuv, and leaflet.

A couple of days ago, I built a Shiny app that lets people use their web browsers to plot counts of terms in all 16 US National Security Strategy reports as a way to explore change over time in US national security concerns (here).

If you click on that link, you'll get what looks like a dead page, or at least a mummified one. In fact, the app still works. It's just that it's been such a hit -- in a social-science, data-nerd kind of way -- that we've already burned through the allotted 25 hours of free monthly server time!

The app should wink back to life in March, or whenever the shinyapps.io billing cycle resets. For now, if you use R or RStudio, you can run the app with these two lines of code (assuming you've already installed the package 'shiny'):

    library(shiny)

    runGitHub("national-security-strategy", "ulfelder")
