Interactive overlays on Shiny plots

Description

overshiny provides draggable and resizable rectangular elements that overlay plots in Shiny apps. This may be useful in applications where users need to define regions on the plot for further input or processing. Currently, the overlays are only designed to move along the x axis of the plot.

Details

The package exports a setup helper (useOverlay()), UI components (overlayToken(), overlayPlotOutput()), a server-side controller (overlayServer()), and a function for aligning overlays to a ggplot2 or base plot (overlayBounds()).
