nullcat 0.2.0

• New feature: weighted pair sampling via wt_row and wt_col parameters. Enables spatially, phylogenetically, or trait-constrained null models by weighting which pairs of rows or columns exchange tokens during randomization. Supported for all sequential algorithms (curvecat, swapcat, tswapcat) and flows through to quantize(), batch functions, trace diagnostics, and vegan integration.

nullcat 0.1.0

• Initial CRAN submission.
• Categorical generalizations of binary null models (curvecat, swapcat, tswapcat, r0cat, c0cat)
• Stratified quantitative null models via quantize()
• MCMC diagnostics (trace_cat, suggest_n_iter)
• Integration with vegan package

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
