Changes in version 1.4-1 (2025-08-26)                  

  - orditkplot: R 4.4.0 deprecated XFig device, and it was defunct and
    removed in R 4.5.0.

  - ordilattice3d failed with vegan 2.8-0 or later.

                 Changes in version 1.4-0 (2025-02-20)                  

  - New function ordilattice3d for 3D ordination graphics using lattice
    package. The function is rudimentary and cannot display biplot
    arrows or centroids. The only advantage over ordiplot3d is that the
    output can be "faceted" or split into panels by external variables.
    
    The function was transferred from vegan where it has been since 2008
    (CRAN release 1.11-0).
    
    The function adds a new dependency on lattice package.

  - ordiplot3d defaults to order axes as horizontal, vertical and
    "depth" so that the front panel is similar as in conventional 2D
    plots.

  - ordirgl failed with argument envfit. Bug report #11.

  - Fixes minor CRAN issues on cross-references to other packages in
    manual pages.

                 Changes in version 1.3-0 (2024-03-19)                  

  - New function orditkplot with its support functions for interactive
    ordination plots. The function will open a new Tcl/Tk window where
    points are fixed at their ordination scores, but their labels can be
    moved to better position with mouse or edited. The plot can be
    exported in various graphics formats or saved in the R session for
    further manipulation or re-created with R commands.
    
    The function was transferred from vegan where it has been since 2008
    (CRAN release 1.11-0).
    
    The function adds a conditional dependency on tcltk package.

                 Changes in version 1.2-0 (2023-02-03)                  

  - Adapted for deprecation of several functions in the rgl package. You
    should upgrade vegan3d together with rgl. See
    https://dmurdoch.github.io/rgl/articles/deprecation.html.

                 Changes in version 1.1-2 (2018-10-25)                  

  - This is a maintenance release to accommodate more stringent tests in
    CRAN. There should be no user-visible changes.

                 Changes in version 1.1-1 (2017-12-01)                  

  - ordiplot3d failed if input was a scores matrix instead of being a
    list-style object.

  - rgl.isomap could fail mysteriously with some extra arguments (e.g.
    with type = "p").

                 Changes in version 1.1-0 (2017-04-24)                  

  - ordiplot3d can now set the exact aspect ratio in ordination plots.
    Earlier we had a kluge that gave approximately correct ratio. The
    package now depends on scatterplot3d version 0.3-40.

                 Changes in version 1.0-1 (2016-06-15)                  

Installation

  - Documentation uses some macros that require R version 3.2.0 or
    higher.

Bug Fixes

  - ordirgl failed when cex was a variable instead of a number.

  - orglcluster did not obey display argument but always showed "sites".

New Features

  - orglellipse gained a new option kind = "ehull" to draw ellipsoid
    hulls or minimum volume ellipsoids that enclose all points of a
    group. The option is based on ellipsoidhull() function (cluster
    package).

  - ordirgl allows suppressing display of environmental variables in
    constrained ordination with envfit = NA.

                 Changes in version 1.0-0 (2015-10-29)                  

General

  - Package was updated to the current rgl (version 0.95) giving a
    facelift to the plots.

Bug Fixes

  - orglspider was not exported.

New Functions

  - orditree3d (based on scatterplot3d) and ordirgltree (based on rgl)
    draw a cluster dendrogram over a 2D ordination or any other plane,
    for instance a map.

  - orglcluster is similar to vegan ordicluster and adds a cluster
    dendrogam to an ordirgl plot.

  - orglellipse is similar to vegan ordiellipse and adds standard
    deviation, standard error or confidence ellipsoids to an ordirgl
    plot.

  - orglspantree is similar to vegan lines.spantree and adds a minimum
    spanning tree to an ordirgl plot.

New Features

  - Users have improved control of colours of plotted items. The colour
    can be a vector for points or text items plotted, or for groups of
    items drawn in the graph (orglellipse, orglsegments, orglspider). If
    the functions draws lines connecting points, the line colour is a
    mixture of colours of connected points (orditree3d, ordirgltree,
    orglcluster, orglspantree, rgl.isomap).

  - ordirgl uses now small spheres instead of points with better visual
    impact.

  - ordiplot3d gained a scores function making easier to add 2D items
    with vegan ordiellipse, ordihull, ordispider, ordisegments etc.

                 Changes in version 0.65-1 (2015-05-27)                 

  - Maintenance release to adapt to new CRAN rules and changes in vegan.

                 Changes in version 0.65-0 (2014-10-07)                 

  - First release version was made by splitting 3D graphic functions
    from vegan. Most of these functions were published in early versions
    (2005 to 2009) of vegan and are are still based on old rgl
    (version 0.65) and do not use the full capabilities of the modern
    package.
