entropart 1.6-15

Bug correction

• PhyloApply() sometimes raised an “Error in m[, 1] : incorrect number of dimensions” due to the automatic conversion of a single-row matrix to a vector by lapply(). This happened when the tree’s upper slice contained a single species.

User-visible changes

• pkgdown site is now built with the bootstrap 5 template.

entropart 1.6-12

Bug correction

• Corrected Coverage() documentation.
• “Marcon” correction of Shannon’s entropy never returned Grassberger’s estimate. This was very rarely an issue.
• Phylogenetic trees of class phylo with multichotomies raised an error when they were preprocessed by Preprocess.Tree().

entropart 1.6-11

Bug correction

• Corrected NEWS file structure.

entropart 1.6-10

Improvements

• Deprecated aes_(x=~var) aesthetics in ggplots replaced by aes(x=.data$var).
• entropart no longer suggests SPECIES.

entropart 1.6-9

Bug correction

• Coverage2Size raised an error when the distribution had no singletons.

Improvements

• entropart no longer depends on ggplot2.

entropart 1.6-8

Bug correction

• An error occured when a function was called with entopart:: prefix and CheckArguments = TRUE and entropart was loaded.

entropart 1.6-7

Bug correction

• argument main in autoplot() was ignored.

Improvements

• Continuous integration by GitHub Actions.
• CommunityProfile() does not recenter simulated diversity values if simulated community size is not that of the actual community. $mid can store mean simulated values.
• CodeFactor recommendations applied.
• col, pch, cex and lty arguments in autoplots.
• The first column of a dataframe passed to MetaCommunity() with species names may be characters instead of factors.
• tibbles are accepted by MetaCommunity().
• Empty communities are detected by Metacommunity() and raise an error with an explicit message rather than returning obscure error messages when used by DivPart() and others.
• Suggests rmarkdown (https://github.com/yihui/knitr/issues/1864)

entropart 1.6-6

Bug correction

• argument main in autoplot() was ignored.

entropart 1.6-4

Improvements

• No longer imports geiger package (required by CRAN).

entropart 1.6-3

New features

• Argument JackMax to limit the order of the jacknife estimator in Richness(), whatever the data.

Bug correction

• plot.SpeciesDistribution did not fit the logseries and the broken stick distributions correctly.
• autoplot.DivProfile did not produce appropriate labels in the local communities profile.

entropart 1.6-1

New features

• Estimation of diversity at a chosen level (sample size or coverage). DivAccum() function.
• Entropy accumulation functions.
• ggplot2 supported. autoplot() methods added for entropart objects.
• The “Best” estimator of diversity is now “UnveilJ” and the default estimator of richness is “Jackknife”.
• The “ChaoWangJost” estimator is renamed “ChaoJost”.

Improvements

• Unit tests added.
• Vignette by pkgdown.

Bug correction

• The jaccknife estimator of richness returned an error for communities where all species had the same abundance.
• Richness returned 0 instead of 1 for a community with a single species.

entropart 1.5-3

Improvements

• On Travis now.
• Reduced package size.
• The rule to calculate the number of individuals of MetaCommunities has been changed to improve gamma diversity bias correction. See the user manual vignette.
• Generic function arguments cleaned up.

Bug Correction

• Very large metacommunities returned an integer overflow error.

entropart 1.4-8

Bug Correction

• HqzBeta() returned erroneous values if a species probability was equal to zero.

Improvements

• On GitHub now.
• Documentation updated: phylogenetic dendrograms can be of class phylo, phylog, hclust or PPtree whatever the function.
• The introduction vignette is HTML now.
• A new vignette is dedicated to phylogenies.

entropart 1.4-7

Bug Correction

• Argument checking (CheckArguments = TRUE) is not possible when the package is not loaded and a function is called by entropart::function(). An error was returned. It is replaced by a warning.

Improvements

• Explicit export of all non-internal functions instead of exportPattern("^[[:alpha:]]+")
• Updated references to published articles.
• Updated help("entropart").
• New introduction vignette.
• Vignettes compiled with knitr instead of Sweave.

entropart 1.4-6

Improvements

• LazyData is used to save memory.
• Better reporting of the argument names in embedded calls of functions.

Bug Correction

• The simulation of log-series communities was incorrect.

entropart 1.4-5

User-visible changes

• Generalized Simpson’s entropy and diversity added (GenSimpson and GenSimpsonD).
• Originality.Species() is deprecated because it is pointless. ade4::originality() allows calculating it for q=2. Leinster (2009) and Leinster and Meckes (2015) showed that Originality.Species() does not depend on the order of diversity.

Improvements

• ZhangGrabchak estimator of entropy is now calculated by the C code of EntropyEstimation::Tsallis.z/Entropy.z rather than the R code of bcTsallis(). This is much faster when the number of individual is high. Applies to ChaoWangJost (Best) estimator too.

entropart 1.4-4

User-visible changes

• DivProfile() now allows computing bootstrap confidence intervals.

Bug Correction

• The entropy estimation (of order different from 1) of a distribution with no singleton returned NA with ChaoWangJost correction. Reported by Zach Marion. Only partly corrected in Version 1.4-1. Corrected.
• DivEst returned incorrect beta diversity if q was not 1. Corrected.

entropart 1.4-3

User-visible changes

• All scalar values of diversity or entropy are now named. Their name is the bias correction used to obtain them.
• The Unveiled estimator is more versatile. Correction = "Unveil" is deprecated and replaced by UnveilC, UnveiliC or UnveilJ in functions such as Tsallis() or Diversity().

Improvements

• Parallelization of DivProfile(), CommunityProfile() and PhyloApply() using the parallel package mclapply. No effect on Windows, pretty much faster on other systems.
• Extensive use of vapply() instead of sapply() makes some functions faster.
• AllenH() and ChaoPD() returned NA if the tree contained more species than the probability vector. Now, the tree may be pruned or kept unchanged and extra species considered to have probabilities 0.

Bug Correction

• Using phylog trees in AllenH and ChaoPD() returned erroneous unnormalized diversity (divided by two) because of the conVersion of phylog to htree divides branch lengths by two. Corrected.
• The richness estimator iChao1 returned NA if the distibution contained singletons but no doubletons. Corrected.

entropart 1.4.1

New Features

• phylog objects (deprecated in ade4) are replaced by phylo trees from package ape in the definition of the PPtree class. Issues caused by phylog such as replacing . and - by _ in species names do not occur any longer. phylog trees are still accepted for compatibility.
• ChaoPD() and AllenH() now accept phylo trees.
• Richness now returns a named value. The name contains the estimator used.
• Updated CITATION: the paper about this package has been published: Eric Marcon, Bruno Herault (2015). entropart: An R Package to Measure and Partition Diversity. Journal of Statistical Software, 67(8), 1-26.

Bug Correction

• The entropy estimation of a distribution with no singleton returned NA with ChaoWangJost correction. Corrected.
• Entropy or diversity of a vector of zeros returned 0. It now returns NA.

entropart 1.3.3

New Features

• Abundance and probability vector objects. See ?SpeciesDistribution.
• Hurlbert diversity. See ?Hurlbert.
• Optimal.Similarity.
• Miller-Madow estimator of entropy (Miller, 1955) added in bcShannon().
• Chao and Jost (2015) estimator of diversity added in bcTsallis() and bcDiversity(). New “best” estimator.
• Chao et al. (2015) probability estimation of observed species. See ?TunedPs.
• Estimators of the number of species. See ?Richness.
• Abundance Frequency Count of species. See ?AbdFreqCount.
• Community profiles can be calculated with confidence intervals. See ?CommunityProfile.
• Random Communities. See ?rCommunity.

Bug Correction

• Applying bcTsallis and similar functions with a probability vector instead of abundance values could cause errors depending in the correction. Correction is now forced to None with a warning.
• Allowed rounding error was too small on some systems (typically r-patched-solaris-sparc) to recognize probability vectors. The difference between their sum and 1 had to be less than 3 times .Machine$double.eps. Now set to S times (where S is the number of species, i.e the vector’s length).

entropart 1.2.1

New Features

• Zhang and Grabchak (2014) bias correction for Shannon beta entropy added.
• Unbiased estimator of Rao’s entropy added (bcRao).

Bug Correction

• DqZ() and Hqz() returned an error if all probability values were 0 except one.

Improvements

• Improved formating of summmary.DivPart(). Lines were too long.
• Improved legend for the x-axis of plot.DivPart (“alpha and gamma” instead of “alpha/gamma”).
• Improved support of PhyloValue objects (summary added).
• Improved help for MetaCommunity.

New Features

• Zhang(2012) bias correction for Shannon entropy added.
• Zhang and Grabchak (2014) bias correction for Tsallis entropy added.

Bug Correction

• Divest() always calculated neutral diversity of simulated communities so the confidence interval was erroneous for phylodiversity. Corrected.

entropart 1.1.3

New Features

• Paracou618.dist distance matrix between species of Paracou618.MC added.
• Chao, Wang and Jost (2013) bias correction for Shannon entropy added.
• EntropyCI function added: Entropy of Monte-Carlo simulated communities.
• Tools to manipulate MetaCommunity objects added (see ?MergeMC).
• SimTest class added to test a value against a simulated distribution (see ?SimTest).
• Vignette added.

Improvements

• Imports directive rather than Depends for ade4.
• mergeandlabel does not return warnings any longer (column names are better addressed).

Bug Correction

• Hqz() was erroneous for q<>1. Corrected.
• bcPhyloEntropy() and bcPhyloDiversity() returned an incorrect $Distribution component. Corrected.
• summary.MCentropy() did not return the name of the tree. Corrected.
• Legend was not displayed in plot.DivProfile(..., Which="Communities"). Corrected.
