simdata() now includes the new
jitter.base parameter, which allows controlled stochastic
perturbations of site-level parameters. This feature increases
variability among simulated communities, particularly in nested designs
(e.g., sites within regions), where previous versions tended to generate
unrealistically similar communities. By applying mild randomness to
occurrence and abundance probabilities, simdata() produces
simulated data sets with multivariate dispersion closer to empirical
expectations.
The use of jitter.base is optional (default
jitter.base = 0), so existing workflows remain unchanged.
Users who wish to reproduce the behavior of earlier versions can simply
ignore this parameter. For reproducibility, remember to use
set.seed() before calling simdata().
