BioTIMEr 0.3.0 - 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.
