Questions tagged [shiny]

Shiny is an R package that makes it easy to build interactive web applications using only R. For the Python Shiny package, use the tag [py-shiny] instead.

Shiny makes it easy for R developers to turn their analyses into interactive web applications that anyone can use, without requiring any prior HTML, CSS or JavaScript knowledge. It enables the developer to let users choose input parameters using user friendly controls like sliders, drop-down menus, and text fields, which will then influence any number of outputs like plots, tables, and summaries.
