Create and Navigate Large Multi-Panel Visual Displays

An extension of Trellis Display that enables creation, organization, and interactive viewing of multi-panel displays created against potentially very large data sets. The dynamic viewer tiles panels of a display across the screen in a web browser and allows the user to interactively page through the panels and sort and filter them based on "cognostic" metrics computed for each panel. Panels can be created using many of R's plotting capabilities, including base R graphics, 'lattice', 'ggplot2', and many 'htmlwidgets'. Conditioning is handled through the 'datadr' package, which enables 'Trelliscope' displays with potentially millions of panels to be created against terabytes of data on systems like 'Hadoop'. While designed to scale, 'Trelliscope' displays can also be very useful for small data sets.
