INTRODUCTION

With flexdashboard, you can easily create interactive dashboards for R. What is amazing about it is that with R Markdown, you can publish a group of related data visualizations as a dashboard.

Additionally, it supports a wide variety of components, including htmlwidgets; base, lattice, and grid graphics; tabular data; gauges and value boxes and text annotations.

It is flexible and easy to specify rows and column-based layouts. Components are intelligently re-sized to fill the browser and adapted for display on mobile devices.

In combination with Shiny, you can create a high quality dashboard with interactive visualizations.
