Calculation of IBD Probabilities R package statgenIBD version 1.0.11 CRAN Task View: Agriculture (https://CRAN.R-project.org/view=Agriculture) For biparental, three and four-way crosses Identity by Descent (IBD) probabilities can be calculated using Hidden Markov Models and inheritance vectors following Lander and Green (<https://www.jstor.org/stable/29713>) and Huang (<doi:10.1073/pnas.1100465108>). One of a series of statistical genetic packages for streamlining the analysis of typical plant breeding experiments developed by Biometris.
