• IMPORTANT: Functions for Community Trajectory Analysis were moved to package ‘ecotraj’, available at GitHub (https://github.com/emf-creaf/ecotraj/) and soon also in CRAN.

Version 1.8.0

• Update of function ‘trajectoryAngles2D’ by Anthony Sturbois

Version 1.7.9

• New option to ‘trajectoryLengths’ and ‘trajectoryAngles’ to calculate distances and angles relative to initial survey
• New functions ‘trajectoryLengths2D’ and ‘trajectoryAngles2D’ by Anthony Sturbois
• Bug correction in vegdiststruct
• Update of CTA vignette (suggestions P. Legendre)

Version 1.7.8

• New option to ‘trajectoryPCoA’ and ‘trajectoryPlot’ to draw survey labels

Version 1.7.7

CRAN release: 2019-01-08

• Bug correction ‘stratifyvegdata’

Version 1.7.6

• Adapt to Rcpp changes

Version 1.7.5

• Now trajectory angles are measured between the direction of the first segment and the direction of the second segment.
• Now mean and sd of trajectory angles are calculated using functions of package ‘circular’
• Parameter ‘add’ added to community trajectory analysis to deactivate constant addition in triplets violating the triangle inequality.
• Update “centerTrajectories” according to Anderson (2017)
• Improved CTA vignette

Version 1.7.1

CRAN release: 2017-09-17

• Package encoding. Changed package and author description.

Version 1.7.0

• NEW feature: Trajectory analysis. Functions ‘trajectoryDistances’, ‘trajectoryLengths’ and ’trajectoryPCoA.
• Added option to ‘trajectoryDistances’ to allow different symmetrization functions (e.g. min) in addition to ‘mean’.
