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").
ordiplot3dcan 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.
ordirgl failed when
cex was a variable instead of a number.
orglcluster did not obey
display argument but always showed
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.
orglspiderwas not exported.
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
orglellipse is similar to vegan
ordiellipse and adds standard deviation, standard error or confidence ellipsoids to an
orglspantree is similar to vegan
lines.spantree and adds a minimum spanning tree to an
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 (
orglspider). If the functions draws lines connecting points, the line colour is a mixture of
colours of connected points (
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
