*New*metric:`angles`

, a dimension level 2 metric that measures the angle of the main axis of each dimension in a matrix (in slopes, angles or degrees).*New*metric:`deviations`

, a dimension level 2 metric that measures the deviation of each element from a hyperplane.- Completely rewritten
`char.diff`

function. It now uses a way faster bitwise comparison architecture and comes with different distance methods as well as modular optional arguments on how to treat various special tokens (`"?"`

,`"-"`

,`"&"`

, etc.). This also allows many more distance methods (now including`"hamming"`

,`"manhattan"`

,`"comparable"`

,`"euclidean"`

,`"maximum"`

and`"mord"`

). - all
`dispRity`

functions can now intake a single`"matrix"`

or a`"list"`

of matrices with the same row names and dimensions. The disparity is then calculated directly on all the matrices and summarised as before through`summary.dispRity`

. This option can be used to add uncertainty to disparity calculations. For example in`chrono.subsets`

you can now provide a list of trees and a list of associated ancestral state estimates; or for`custom.subsets`

you can provide a list of matrices with different values representing different estimations of the traits.

- update
`reduce.matrix`

to work with`vegan::vegdist`

version 2.5-6 (thanks to Jari Oksanen for the fix). - updated class evaluations throughout the package for
`R`

version`4.0.0`

:`class(.) == *`

is now`is(., *)`

. - updated
`...`

argument bug PR#16223. - In
`make.metric`

the argument`...`

is now ignored if any`names(...)`

is`"tree"`

or`"phy"`

. - fixed bug in
`neighbours`

and`span.tree.length`

when feeding “distance” like metrics (thanks to Ashley Reaney for finding that one).

- greatly improved speed of
`chrono.subsets`

with`method = "continuous`

(now > 1000 times faster!). - minor warning message fix for
`plot.dispRity`

with time slices. - removed
`paleotree`

package dependency (though the links to this excellent package are still there!). - increased
`R`

version requirement to`3.5`

. `...`

in`summary.dispRity`

are now directly passed to`cent.tend`

(e.g.`na.rm = TRUE`

).- added some time improvements in several phylo functions based on the
`castor`

package. - updated all the package demo data to fit the new
`dispRity`

object architecture (see above). Note that this might effect the exact results of calculations using these demo datasets. - you can now specify the dimensions of the matrix to make a disparity metric in
`make.metric`

through the`data.dim`

option. - metrics passed in
`dispRity`

are now tested using the input data dimensions. `chrono.subsets`

with multiple trees now stretches the root edges length to match the oldest tree.

*New*metric:`displacements`

, a dimension level 2 metric that measures the position of elements in space (i.e. their distance from the centre relative to their distance to their centroid).*New*metric:`neighbours`

, a dimension level 2 metric that measures the distance from an element to its neighbour (e.g. the nearest neighbour, the furthest, the median, etc.).*New*metric:`quantiles`

, a dimension level 2 metric that measures the*n*th quantile range per axis (a good alternative to the`ranges`

function!).*New*metric:`func.eve`

, a dimension level 1 metric that measures the functional evenness (i.e. the spread along the minimum spanning tree; from Villéger et al. 2008).*New*metric:`func.div`

, a dimension level 1 metric that measures the functional divergence (i.e. the ratio of deviation from the centroid; from Villéger et al. 2008).*Updated*metric:`span.tree.length`

now outputs the length of each edges (c.f. the sum of the length) and becomes a level 2 metric.- The
`chrono.subsets`

can now take`multiPhylo`

objects for slicing through multiple trees at once! *New*utility function:`reduce.matrix`

for optimising data overlap in a matrix with missing data.*New*utility function:`slide.nodes`

for sliding specific nodes on a tree.*New*utility function:`remove.zero.brlen`

for stochastically removing zero branch lengths on a tree (using the`slide.nodes`

function).**New argument**in`plot.dispRity`

: the`type`

argument can now be`"preview"`

to have a glimpse at two of the dimensions of the trait-space.- The
`Claddis.ordination`

can now directly take a matrix’s path as input (leaving the function to read and transform the matrix into`Claddis`

format. The function can thus now also be used to convert matrices into`Claddis`

format. - Added a “Other functionalities” section to the manual describing miscellaneous functions.

`centroids`

and`ancestral.dist`

functions can now take the`method`

option for`"euclidean"`

or`"manhattan"`

distances.- All functions methods selection have now been sped up using
`switch`

. - Error messages in
`dispRity`

are more verbose when input the wrong metric(s). `scree`

option in`space.maker`

does not require to sum up to one anymore.`cor.matrix`

option in`space.maker`

does not require to have a valid Choleski decomposition (an approximation is used instead).- Updated all tests and functions to be compatible with R 3.6.
- Fixed bug in
`clean.data`

that did not output dropped tips correctly when applied on`multiPhylo`

objects. - Improved error messages in
`chrono.subsets`

for funky time slices/bins (e.g. with negative values). - Speed improvements for the
`time.slice`

function. - Better internal handling of distance matrices for the disparity metrics.
- Most functions handles
`NA`

as`na.rm`

or`na.omit`

.

`dispRity`

objects now contain a metric argument (if a metric was applied). This argument can now be recycled by the appropriate functions (e.g. in`null.test`

).

`plot.dispRity`

argument`observed`

can now take a list of arguments to be passed`points()`

.`boot.matrix`

can now be used to simply create coordinates matrices (no ordination!) with`ordinate = FALSE`

argument.- better internal handling of error messages.
`faster`

when the argument is left missing.- removed internal handling of the
`Claddis.ordination`

function. This function now uses the brand new version of the`Claddis`

package on CRAN (0.3).

`plot.dispRity`

with option`"box"`

now correctly display plot ranges when disparity is an observed distribution.`test.dispRity`

names are now properly protected in the`C`

implementation to comply with new`rcheck`

requirements.

:`prob`

for passing probabilities of sampling for specific elements.- S3
`print`

method for objects of class`"dtt"`

and`"dispRity"`

(from`dtt.dispRity`

).

- tydiversed most of the error messages.
`dtt.dispRity`

now allows to specify the alternative hypothesis (if`nsim > 0`

).`ellipse.volume`

can now take an explicit eigen value vector (the eigen values are still automatically estimated correctly for PCO and MDS).- Improved metric checking messages from
`make.metric`

when dealing with optional arguments. - Removed cascade of warnings triggered by
`plot.dispRity.dtt`

.

- Corrected
`char.diff`

to properly reflect the probability of different splits between characters (thanks to Abigail Pastore).

`Claddis.ordination`

function.
