Analytical methods include equivalent complete generations, generation intervals, effective population size (via inbreeding, coancestry, and demographic approaches), founder and ancestor contributions, partial inbreeding, genetic diversity indices, and additive (A), dominance (D), and epistatic (AA) relationship matrices. Core algorithms — ancestry tracing, topological sorting, inbreeding coefficients, and matrix construction — are implemented in C++ ('Rcpp', 'RcppArmadillo') and 'data.table', scaling to pedigrees with over one million individuals. Pedigree graphs are rendered via 'igraph' with support for compact full-sib family display; relationship matrices can be visualized as heatmaps. Supports complex mating systems, including selfing and pedigrees in which the same individual can appear as both sire and dam.https://github.com/r-universe/luansheng/actions/runs/27463604020Tue, 14 Apr 2026 03:59:54 GMTvisPedigree1.8.1successhttps://luansheng.r-universe.devhttps://github.com/luansheng/vispedigreetidy-pedigree.Rmdtidy-pedigree.htmlHow to tidy a pedigree 2018-11-14 08:34:522026-03-25 11:43:04efficient-visPedigree-workflows.Rmdefficient-visPedigree-workflows.htmlEfficient visPedigree Workflows 2026-03-15 08:32:542026-03-15 09:27:27draw-pedigree.Rmddraw-pedigree.htmlHow to draw a pedigree 2018-11-14 08:34:522026-04-14 03:59:54pedigree-analysis.Rmdpedigree-analysis.htmlPedigree Analysis and Population Genetics 2026-03-14 02:27:242026-03-25 10:54:54relationship-matrix.Rmdrelationship-matrix.htmlCalculation and visualization of relationship matrix 2026-01-20 14:18:282026-03-23 07:25:42tidyped-structure.Rmdtidyped-structure.htmltidyped Class Structure and Extension Notes 2026-03-15 08:32:542026-03-25 11:36:01
