Changes in version 31.07.2024 - Update of the vignette for clarity - FIX of the Mac M1 specific issue happening in package dggridR - FIX in resampling() to sample without replacement - FIX in getLinearRegressions() to correct result dimensions and metric order Changes in version 29.11.2025 Major Improvement - The package now uses data.table in the background for major speed and memory usage improvements. Resampling the whole BioTIME database used to take > 1 hour and now takes < 1 minute. - methods: gridding and resampling functions now handle data.frame, data.table and tibble objects with dedicated functions. - getAlphaMetrics and getBetaMetrics are faster and use 100x less memory. New Features - In the resampling function: - new argument summarise, TRUE by default keeps previous behaviour. If TRUE, the abundance and/or biomass is summed per rarefyID while if FALSE the abundance and/or biomass will be summed per rarefyID/SAMPLE_DESC and gives more columns. - In the getAlphaMetrics and getBetaMetrics functions: - data.frames containing several resamplings are accepted If the provided data contain several resamplings, metrics will be computed per resampling, per assemblageID, per year. - In the getLinearRegressions function: - removed the divType argument. The function now reads the class of the objects produced by getAlphaMetrics and getBetaMetrics and computes the expected metrics. Minor Improvements and Bug Fixes - In the themeBioTIME function: - argument lp is soft deprecated in favour of legend.position - argument fontSize is soft deprecated in favour of font.size - argument colx is soft deprecated in favour of axis.colour - argument coly is soft deprecated in favour of strip.background - the order of the arguments did not change. Changes in version 19.09.2025 - Patch. all testthat snapshot tests are now skipped on CRAN and CI. Changes in version 10.03.2026 Minor Improvements and Bug Fixes - Documentation for data sets BTsubset_data and BTsubset_meta was improved. - Figures in the vignette were invisible. Changes in version 10.02.2026 Minor Improvements and Bug Fixes - getLinearRegressions() now handles data from getMetrics() with several resamplings. - getMetrics() and getLinearRegressions() now work without resamplings allowing users to run them on their own data. - vignette YAML frontmatter fixed. Changes in version 06.06.2025 - Data update matching structure from BioTIME v2.0. Changes in version 03.04.2024 - Initial CRAN submission. Changes in version 0.2.6 (2025-10-15) - Patch. test modification to adapt to vegan update 2.7-2
