dygraphs

The dygraphs package provides an R interface to the dygraphs JavaScript charting library for creating interactive time-series visualizations. It works directly with xts time series objects and any data convertible to xts format.

The package offers interactive features like zoom, pan, and point highlighting that make exploring temporal data easier. It supports customizable axes including optional secondary Y-axes, overlays for uncertainty intervals and annotations, and integrates seamlessly with R Markdown documents and Shiny applications. These features make it particularly useful for exploratory time-series analysis and creating interactive reports.
