Momocs 1.4.1 (2023-11-13)

Removed rgeos dependency so that Momocs can resurect on CRAN

Momocs 1.4.0 (2022-04-04)

Fixed several minor bugs, mostly with plotting.
coo_slide duplicated the initial point in some cases. Now fixed.
coo_likely_clockwise (and friends) now uses complex numbers and is much more robust.
removed some annoying messages.
slice(..., 1) now returns a matrix for $coe, not a numeric ([,,drop=FALSE])
I'm currently out of academia and I'm looking for funding to develop MomX. I plan to give some of my time in 2022 and after but if you have any ideas, either directly or through hiring me for consulting, ring my bell!

Momocs 1.3.3

plot_PCA and plot_LDA did not consistently work within eg pdf(). Thanks to Bill fof pointing this. (214)
coo_shearx/y did not return the Coo. Fixed.

Momocs 1.3.2 (2020-10-06)

Turned remaining return for return() to please R CMD check
as_df now uses tibble verbs everywhere
printing Coo is faster now at the price of sampling 100 shapes on which to calculate the mean number of coordinates and their sd.
Removed the (quite) annoying startup message. I will not have time for MomX until 2021 anyway

Momocs 1.3.1

Changed all dplyr::as_data_frame for tibble::as_tibble

Momocs 1.3.0 (2020-04-15)

This version will be the last major one released on CRAN. Momocs is now retired and will no longer be maintained. See momx.github.io. As of April 15, 2020 it satisifies all available testing approaches.
new multivariate method: KMEDOIDS on top of cluster::pam. Added a plot_silhouette to go with this friend. Now depends cluster.
new multivariate method: NMDS on top of vegan::metaMDS; use plot_NMDS to plot it and vegan::stressplot for a Shepard plot. Now depends vegan.
new multivariate method: MDS on top of cmdscale; use plot_MDS to plot it.
mshapes is now MSHAPES to stick with other capitalized "multivariate" methods. mshapes now just announces its future deprecation.
MSHAPES now just returns data_frame of PCs or LDs when used on PCA or LDA objects.
Consequently, plot_MSHAPES is the new method for plotting it. Works on lists and on the result of MSHAPES.
plot_CV has been refreshed, and is better now at plotting either small or very big matrices.
fac_dispatcher supports NULL which eases a lot multivariate plots (notably Momecs side)
new handling method rm_missing to deal with missing data in $fac
boxplot methods on Coe have been refreshed
hist methods on Coe deprecated
coo_plot no longer a method and gains a cex.first.point argument
new method: coo_scalars that gather all scalar descriptors of shape
TraCoe class properly data_frameize fac when build from TraCoe()
CLUST methods have been rewrote and now wraps around dendextend.
Consequently released ape dependency.
all morphometrics methods now accepts lists which is more elegant when working with chop+combine
LDA methods have been partly rewritten and now handles constant and collinear variables by dropping them and storing them in the returned list
morphospace on LDAs are (finally) back, yet still quite experimental.
coo_untiltx now removes (residual) rotational biases after coo_slidedirection and should be used after it.
plot_LDA now on. Pretty much the same as plot_PCA (which was expected yet nice).
.layerize_LDA as an internal to prepare the previous
new vignettes: Momocs_coo and Momocs_FAQ; others refreshed.
morphospace_position and chullfilled in plot_PCA now properly working
verify replaces validate to avoid conflict with shiny::validate (for Momecs)
subsetize now exported (again)
def_ldk gains a close and points argument
no more printing of Coo errors that was due to some forgotten data.frame rather than data_frame
all Coo builders gain a .data.frame method, notably to ease compatibility with Momit
as_df now returns more useful data_frame everywhere and gain a retain argument
deprecated coo_angle_edge1 and friends, now in coo_angle_edges see 1.2.9.
fixed minor bugs (see GitHub history of commits)

Momocs 1.2.9 (2018-03-22)

Preamble

Started a general review of Momocs (including #184) to prepare for MomX. For my convenience, all changes will stack on 1.2.5 on GitHub but will appear, in the end, as 1.9.0 on CRAN to both reflect proximity with 2.0 and the huge quantity of changes since 1.2
Moved everything to github.com/MomX/Momocs
ongoing complete review of code
ongoing complete review of manual pages: lots of grouping, more and better
graphics is not dead (aka grindr): pipe-friendly base layers for biplots and shape drawing on cartesian coordinates. Is used to replace all multivariate plotters (eg plot.PCA), family pictures (eg stack will be replace by pile and remove an annoying conflict with utils::stack, panel) and single shape plotters (eg ldk_plot, coo_plot). This strategy is faster, much more generic and will ease further development and maintenance compared to previous Momocs graphs.
A vignette details grindr rationale and use.

New

new functions: andnow and andnow_method class tells you what to do with this object, and which classes are supported by this function/method.
new coo_* methods: coo_range, coo_range_enlarge, coo_diffrange, coo_template_relatively. The latter will prepare ground for proper size handling, notably for morphospaces.
Many coo functions ported to methods and now supporting .Coo directly: coo_angle_edges, coo_angle_tangent, coo_boundingbox, coo_calliper, coo_chull, coo_chull_onion, coo_circularity, coo_circularityharalick, coo_circularity_norm, coo_convexity, coo_dxy, coo_eccentricityboundingbox, coo_eccentricityeigen, coo_elongation, coo_intersect_angle, coo_intersect_direction, coo_intersect_segment, coo_perim, coo_perimcum, coo_perimpts, coo_rectangularity, coo_rectilinearity, coo_scalex, coo_scaley, coo_solidity, coo_truss.
Palettes are now those colorblind-friendly from RColorBrewer and those, state of the art, virids palettes. See also pal_manual, pal_qual_solarized and pal_seq_grey.
dispatch_fac is now behind all fac arguments
fgProcrustes now accepts lists
efourier with default norm=TRUE now messages about how wrong it may be
dplyr::tibble() everywhere pertinent

Deprecated

All is.* aliases for is_* methods
Deprecated classify for a while
All calibrate_*(..., method) have been renamed to calibrate_*_method. See ?calibrate_reconstructions and friends.
Deprecated plot3.PCA (will be replaced in further versions)
Ntable now splitted into of plot_table + table
coo_tangle now in coo_angle_tangent
coo_theta3 now in coo_angle_edges
truss now in coo_truss and a method of its own
plot.Coo is now inspect
pos.shapes is now morphospace_positions
is_closed is deprecated, now coo_is_closed; same for is_open now coo_is_open, to comply with all coo_* friends naming scheme
is_clockwise is deprecated, now coo_likely_clockwise; same for is_anticlockwise now coo_likely_anticlockwise. Better reflect the incertainty and gather with coo_* friends
Deprecated table (poor shortcut anyway and avoid this boring startup message)
Deprecated stack2 and panel2 before their rewriting
Deprecated as_Out, that should have been efourier_i.OutCoe anyway.
Consequently deprecated panel.OutCoe method that was additionnaly the only Coe method. May be back in further versions.
Some non-exported functions (ie internals) now homegeneously begin with a ., eg .is.error (try Momocs:::. + <Tab> for a complete list).
Some previously exported functions are now internals (function_foo renamed to .function_foo): .coo_angle_edge1, .vecs_param, .refactor
NEWS is now a decent NEWS file
Online doc has been moved to [http://momx.github.io/Momocs/]

Dependencies

Released reshape2, plyr dependencies
Now depends RColorBrewer, progress
Proper indications of external functions with ::. A nice side effect is to remove annoying messages when attaching Momocs. Another is the removal of most importFrom.

Breaking changes

Besides deprecated/renamed functions there should be no breaking changes.
Future breaking changes are announced within concerned functions.

Release on CRAN that replaces the now completely obsolete 0.2.6 (the one from the JSS paper.
It consists of the last version pushed to CRAN.

Momocs 0.9

Started to routinely use GitHub (and NEWS)
a complete rewriting of the package, and the inclusion of new morphometrics approches (open outlines, configuration of landmarks, global shape descriptors).
New design with classes Out, Opn and Ldk to handle (closed) outlines, open outlines and configuration of landmarks. Coo becomes a "super class" encompassing the three others.
S4 -> S3 rewriting. Maybe less orthodox but much more easy to understand, code, extend which is probably the most required for Momocs at this step.
Renaming of functions/methods in a more consistent scheme
New/partial rewriting of multivariate methods: MANOVA, MANOVA_PW, LDA, KMEANS, CLUST.
Graphics have been refreshed: panel, stack, plot.PCA
New datasets: chaff, flowers, oak, olea, molars, shapes, wings,
