Package: fastphylosig Type: Package Title: Fast Phylogenetic Signal Statistics Version: 0.3.1 Authors@R: person("Yin", "Wen", role = c("aut", "cre"), email = "wenyinsci@126.com") Description: Provides one-command and method-specific workflows for phylogenetic signal in continuous, binary, and categorical traits. Compiled tree-pruning algorithms implement Blomberg's K and Pagel's lambda without constructing a dense phylogenetic covariance matrix in production. Fritz and Purvis D retains separate random and Brownian null models, while categorical Delta combines discrete ancestral-state likelihoods with MCMC and permutation diagnostics. The package also provides reusable prepared trees, explicit tree/data matching, trait-wise missing-value handling, conservative tree diagnostics, bounded simulation memory, and structured timing and Monte Carlo uncertainty metadata. Methods follow Blomberg, Garland and Ives (2003) for K, Pagel (1999) for lambda, Fritz and Purvis (2010) for D, and Borges et al. (2019) for categorical Delta.
