The manipulateWidget package is largely inspired by the manipulate package from Rstudio. It provides the function `manipulateWidget that can be used to create in a very easy and quick way a graphical interface that lets the user modify the data or the parameters of an interactive chart. Technically, the function generates a Shiny gadget, but the user does not even have to know what is Shiny.
The package also provides the combineWidgets function to easily combine multiple interactive charts in a single view. Of course both functions can be used together: here is an example that uses packages dygraphs and plot_ly (code at the end of the document).
