CRAN release 2.6-8

Many things change, but most changes are minor bug fixes or improved features. Perhaps the most visible change is adding pca, ca and pco functions for unconstrained ordination. For detailed changes, check NEWS.

Critical Bug Fix 2.6-6.1 on CRAN

Internal C function had a "protection error" which could crash R in unpredictable and non-repeatable ways: Function could run quite normally hundreds of times and then crash. The C function was used in several R functions, and errors could occur, e.g. in envfit (especially vectorfit), wcmdscale, capscale and varpart of Chi-square. The release is identical to 2.6-6 except for this bug fix. You should absolutely upgrade.

vegan 2.6-6 on CRAN

See NEWS for new things. The main thing may be unbiased permutation code for CCA significance tests.

This release will break (or prepare to break) some old things.

• adonis is deprecated in favour of adonis2. We have had a deprecation message from vegan 2.6-2 (April 2022), but now this was turned into a warning. Instructions for changing your code are given in #641.
• We deprecate the use of summary to get ordination scores: use scores() instead. As this is a side effect we do not know if you misused summary for scores and we cannot warn. For this release we still enable this bad habit, but you should change your code. Instructions are given in #644.
• Further changes and planned new features are discussed in #645.

vegan 2.6-4 on CRAN

This version has numerous changes all over the code, but nothing very dramatic. Many people may like improved support for making ggplot2 graphics with scores function optionally producing data frames that can be directly used for flexible graphics. For an extensive and detailed description of changes, see NEWS.

vegan 2.6-2 in CRAN

New CRAN release was based on the current master branch. The old cran-2.5 will no longer be updated. For details of changes, see the NEWS in the package. Use command news(package="vegan") in R session to read the news.

Here a brief summary:

• Compiled code was fixed for upcoming R 4.2.0 release, and you must upgrade vegan with new R.
• Several functions can now return their results in tidy format allowing easier use of ggplot2 graphics.
• adonis2 is the new major function for analysis of dissimilarites. The old adonis is still available, but it will be deprecated in the next minor release.
• Aitchison and robust Aitchison distances and standardization were added.
• Unbiased Simpson diversity was added, and diversity gained a groups argument for pooled diversities.
• Following github issues were addressed: #369, #393, #401, #427, #447, #463, #497, #501, #507.

CRAN release 2.5-7

This release fixes github issues #352, #354, #369, #372, #374 and #382.

vegan 2.5-4 released

Bugs were fixed in decorana (issue #303) and goodness.cca and also documentation glitches (issue #304). Adjusted R² is again enabled in rda and cca (issue #295).

CRAN release 2.5-3

• passes CRAN tests more cleanly with alternaltive BLAS/Lapack libraries (issue #282).
• Fixes handling empty data in constrained ordination (issue #291).
• Checks for valid numerical input in several functions (issues #284, #292).
• Fixes handling missing values in envfit.
• Fixes scalilng of rda results in simulate.
• Improved checking of valid input in anosim.
• Refuses to show Broken-stick distribution when there are negative eigenvalues in dbrda.
• print method for betadisper is more configurable.
• Deprecates humpfit which is moved to natto package (issue #289).

CRAN release 2.5-2

vegan 2.5-2 was released on the Norwegian Constitution Day, 2018 (happy syttende mai!). This is a minor maintenance release. See discussion in issue #280 for main features.

CRAN release 2.5-1

This is a major new release. Nearly 40% of all program files were changed. The most significant changes were that compiled code (with .Call interface) is used much more extensively, constrained ordination methods were refactored to use unified code base, and ecological null models were made made more effective. See the NEWS file in the latest release for detailed changes.
