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

vegan 2.5-7 was released to CRAN on Nov 28, 2020. See NEWS for most important changes.

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

vegan 2.5-4 released

vegan 2.5-4 was released on CRAN. This fixes testing errors in R-devel due to changes in formula (issue #299) and errors with new optional tests in R-devel (issue #305). 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.

CRAN 2.4-4 release

This is a minor release that fixes the following issues

• orditkplot passes CRAN tests.
• anova(<cca-object>, by = "axis") ignored partial terms. Function uses now forward testing which is less dangerously biased than previous marginal tests.
• summary and inertcomp for RDA, CCA and frieds failed if constraints had zero rank.
• meandist labels are no longer cropped in plots.
• Canberra distance in vegdist can now handle negative entries in input.

CRAN release 2.4-3

• Registers C and Fortran routines: no longer NOTE in checking the package.
• Fixes weighting issues with cca result object: changes in centring of biplot scores, in as.mlm methods, and in intersetcor and spenvcor.
• Allows correlation scaling in biplot.rda.
• Allows using species scores in envfit and ordisurf.
• Allows using non-standard variable names in Condition in constrained ordination method.
• Fixes issues in ordiR2step and only allows forward selection.
• Allows configuration of ordispider plots for WA/LC scores in constrained ordination.
• Fixes several issues in tolerance.cca

CRAN release 2.4-2

vegan 2.4-2 was released in CRAN on 17/1/17. The release contains more complete NEWS. The major changes are:

• Fixes permutation tests in distance-based constrained ordination (issue #198, PR #199).
• Fixes internal scaling of scores in some constrained ordination methods.
• Fixes weighting in intersetcor
• Fixes issue #219 in betadisper permutation tests.
• Fixes (invisible) return object of ordicluster.
• Fixes tolerance.cca (issue #216).
• Changes scaling of biplot arrows in constrained ordination plots.
• Adds new argument and improves colour coding of small positive values in tabasco.
• Faster nullmodel generation.
• Faster vegdist.
• More robust handling of formula which also fixes issue #200.
• Updated taxonomy of dune meadow species.
