coda.plot 0.2.2
===============
New features
  * Added a modular API for ternary diagrams based on ternary_frame(),
    ternary_plot(), ternary_coords(), add_ternary_grid(),
    add_ternary_points(), add_ternary_path(), and add_ternary_pc().

Improvements
  * Improved ternary plotting so that corner labels are inferred from
    colnames(X) when available, and refreshed automatically when the
    initial frame used default labels.
  * Added optional centering and scaling in log-ratio coordinates to
    ternary_frame() and ternary_diagram().
  * Added support for plotting principal component directions in ternary
    diagrams through add_ternary_pc() and the show_pc argument of
    ternary_diagram().


coda.plot 0.1.9
===============
* balance_dendrogram() indexing corrected.
