SSP 1.1.0

Function adjustments

• simdata() now includes the newjitter.base parameter, which allows controlled stochasticperturbations of site-level parameters. This feature increasesvariability among simulated communities, particularly in nested designs(e.g., sites within regions), where previous versions tended to generateunrealistically similar communities. By applying mild randomness tooccurrence and abundance probabilities,simdata() producessimulated data sets with multivariate dispersion closer to empiricalexpectations.

• The use ofjitter.base is optional (defaultjitter.base = 0), so existing workflows remain unchanged.Users who wish to reproduce the behavior of earlier versions can simplyignore this parameter. For reproducibility, remember to useset.seed() before callingsimdata().

SSP 1.0.2 (2025-04-23)

Changes requested by CRAN

• Updated cross-references in.Rd files to use explicitpackage anchors (e.g.,\link[ggplot2:ggplot2-package]{ggplot2}) as requested bythe CRAN team.
• Removed all\link{} usages without package anchors indocumentation files.
• Ensured compatibility with HTML reference manuals.

Documentation improvements

• All .Rd documentation files were migrated to theroxygen2 format.
• Improved consistency and accuracy in the documentation of functionarguments and outputs.
• Added missing imports in the NAMESPACE to fix visibility issues(ggplot,geom_point,specnumber,etc.).
• Removed unused@importFrom tags and documented onlynecessary dependencies.

Code adjustments

• Replaced use ofrel() inplot_ssp() toavoid dependency ongrid::rel, which is not exported.
• Reformatted long lines in examples to comply with CRAN’s100-character limit.

Testing and validation

• devtools::check() returns0 errors | 0 warnings| 1 notes (only minor ones related to timestampverification).
