VEGAN STABLE VERSIONS 

Version 1.4-0
=============

Based on devel version 1.3-19.

New functions:
--------------

* `anosim': Analysis of Similarities.

* `cca': [Partial] [Constrained] Correspondence Analysis.  This is an
  alternative to Dray's `CAIV' (package `CoCoAn').  Differences
  include formula interface, WA scores in addition to LC scores,
  partial CCA, residual CA after constraints, algorithm based on svd
  (and much faster), more standard support functions (`plot',
  `summary', `print').

* `anova.cca' and `permutest.cca': Permutation tests for `cca'.

* `envfit': A new wrapper function which calls either `vectorfit' or
  new `factorfit' function, and `plot.envfit' for easier display of
  results in graphs.

* `mantel': Mantel test for two dissimilarity matrices.

* `scores': A generic function to extract scores from `cca',
  `decorana' or even from some common ordination methods in R.

* `surf': Surface fitting for ordination, intended as an alternative
  to `vectorfit'.

* `vegetab': Prints a compact, ordered vegetation table, together with
  `coverscale' to transform data into compact format.

Other changes:
--------------

* `downweight': directly callable instead of being embedded in
  `decorana'. Now it can be used with other downweighting thresholds
  or with other CA's than `decorana', e.g., `cca', `ca', `CAIV'.

* `plot.decorana': new keyword `type', removed keyword `tol'.

* `vectorfit': centres now ordination before fitting, so it will work
  with other ordinations than MDS.

* Mainly user invisible changes in `plot.decorana', `plot.procrustes',
  `postMDS', `print.summary.procrustes', `vectorfit', `procrustes'.
  One of the main changes was that `eqscplot' of `MASS' library was
  replaced with `plot(..., asp=1)' of standard R (but this is not
  S-plus compliant).

* Edited help files.  More examples run from help files.  

* Tried to improve LabDSV compliance, see http://labdsv.nr.usu.edu/.

* Checked with R-1.5.0.  However, `log' in diversity not changed into
  `logb' (yet), although base is specified, because `logb' won't work
  in R pre-1.5.0. 

Version 1.2-1
=============

* Checked with R-1.4-0 (frozen snapshot) tools: Documentation and
  method consistency corrected (summary.decorana.R, decorana.Rd), and
  file permissions changed.

* decorana.Rd: removed dependence on package `multiv' in the example,
  since it is not a `recommended package' -- replaced with
  `decorana(..., ira=1)'.

Version 1.2-0
=============

Based on experimental version 1.1-6. Doesn't include read.cep() of the
experimental version, because the function is certainly unportable to
all platforms (works on Red Hat Linux 7.1, but perhaps nowhere else).

Major new feature:

* decorana(): R port of Mark Hill's DECORANA for Detrended
  correspondence analysis, with methods print(), summary() and plot().

Minor changes:

* postMDS(): finds isoMDS scores and doesn't destroy list structure.

* vectorfit: finds isoMDS scores and decorana row scores (which are
  uncentred, though).

* Proof reading in documentation.

Version 1.0-3
=============

* `plot.procrustes': selection of axes plotted, improved scaling in
  graphics, control of axis labels.

* `postMDS': added plot to demonstrate half-change scaling. 

* `procrustes': target can now have lower dimensionality than rotated matrix.

Version 1.0-2
=============

* Fixed bugs in documentation.

* `plot.procrustes': Fixed passing `...' to graphics functions.

Version 1.0-1
=============

* The first public version.
