echarty

This package is a thin R wrapper around Javascript library ECharts.
One major command(ec.init) uses R lists to support the ECharts API.
Benefit from ECharts full functionality and build interactive charts in R and Shiny with minimal overhead.

Wider connectivity and deployment potential through WebR and crosstalk.

Get started

The Coder is a good introduction, type library(echarty); demo(coder).
The WEBSITE has a vast gallery with code and tutorials.
The package itself has also code examples included. Type ?ec.examples, then copy/paste any code to see the chart.

Now you can start building beautiful ECharts (and more) with R and Shiny!
