The vegan3d package provides 3D plotting for all vegan
ordination methods or any other ordination method that vegan
scores function can handle. It can also display
hclust results in 3D over a 2D plane. Dynamic 3D plots
are based on the rgl package and static plots are drawn with the
Index: This package was not yet installed at build time.
The rgl graphics are dynamic 3D plots that can be spinned and
zoomed by mouse. The vegan3d package provides interface to
ordination and clustering objects. The functions use rgl setting
and conventions and do not change the user settings. For general
configuration of the plots, users should check rgl
documentation. For instance, general look and feel of drawn items can
be configured with
The rgl package may not be available in all platforms, and
therefore the package is not automatically attached. If you want to
use rgl functions, you must either prefix commands with
rgl:: or call
library(rgl) in your session.
ordirgl is simalar as
ordiplot in vegan, and any ordination
result can be drawn with similar conventions. Functions with
orgl prefix add items to existing plots, for instance,
orglellipse is analogous to
ordirgltree draws an
dendrogram over a plane. It was originally developed for 2D ordination
planes, but any other plane can be used, for instance a projected map.
provide alternative dynamic 3D plots for vegan
The scatterplot3d package draws static 3D graphics, and
vegan3d provides an interface for ordination and clustering
objects. You must consult the
scatterplot3d documentation for
configuring your plots.
ordiplot3d is similar to
ordiplot and draws a static 3D plot in the
standard graphical device. It returns invisibly a plotting object
which contains the projected points, and vegan
prefix functions can use this object. For instance,
ordiellipse will add ellipses on the projected
orditree3d will draw an
dendrogram over a plane similarly as
