Changes in version 2.0.3 (2025-05-19) - Package documentation in Roxygen Changes in version 2.0.2 (2022-08-25) - Bug corrected in medoid-based methods which allowed chosing the same object as medoid for different clusters. Issue was reported by Alexander Bauer (Department of Statistics LMU Munich). - Exclude duplicate objects that are in the same exact position as potential seeds Changes in version 2.0.1 - Translation of vignettes to Rmarkdown Changes in version 2.0.0 (2021-06-01) - 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. Changes in version 1.8.0 - Update of function 'trajectoryAngles2D' by Anthony Sturbois Changes in 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) Changes in version 1.7.8 - New option to 'trajectoryPCoA' and 'trajectoryPlot' to draw survey labels Changes in version 1.7.7 (2019-01-08) - Bug correction 'stratifyvegdata' Changes in version 1.7.6 - Adapt to Rcpp changes Changes in 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 Changes in version 1.7.4 (2018-05-29) - Improvement of parameter checking in function 'stratifyvegdata' - Documentation of avoca data set - New function 'trajectoryPlot' Changes in version 1.7.3 - New function 'trajectoryConvergence' - New function 'trajectoryDirectionality' - New function 'centerTrajectories' Changes in version 1.7.2 - New function 'trajectoryAngles'. - New function 'trajectoryProjection'. - New vignette for trajectory analysis. Changes in version 1.7.1 (2017-09-17) - Package encoding. Changed package and author description. Changes in 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'.
