Mastering Shiny

Shiny user showcase

The Shiny User Showcase is comprised of contributions from the Shiny app developer community. The apps are categorized into application areas and presented with a brief description, tags, and for many, the source code. Note that many of these apps are winners and honorable mentions of our annual Shiny contest!

• 1st contest winners

DT

The R package DT provides an R interface to the JavaScript library DataTables. R data objects (matrices or data frames) can be displayed as tables on HTML pages, and DataTables provides filtering, pagination, sorting, and many other features in the tables.

• Interactive tables

• Tables as inputs

• Editable tables

reactable

Interactive data tables for R, based on the React Table library and made with reactR.

• Sorting, filtering, pagination
• Grouping and aggregation
• Built-in column formatting
• Custom rendering via R or JavaScript
• Expandable rows and nested tables
• Conditional styling

htmlwidgets

The htmlwidgets package provides a framework for easily creating R bindings to JavaScript libraries. Widgets created using the framework can be:

• Used at the R console for data analysis just like conventional R plots (via RStudio Viewer).
• Seamlessly embedded within R Markdown documents and Shiny web applications.
• Saved as standalone web pages for ad-hoc sharing via email, Dropbox, etc.

pool

The goal of the pool package is to abstract away the logic of connection management and the performance cost of fetching a new connection from a remote database. These concerns are especially prominent in interactive contexts, like Shiny apps (which connect to a remote database) or even at the R console.
