An R Package for Extended Behavior Genetics Analysis R package BGmisc version 1.6.0.1 Provides functions for behavior genetics analysis, including variance component model identification [Hunter et al. (2021) <doi:10.1007/s10519-021-10055-x>], calculation of relatedness coefficients using path-tracing methods [Wright (1922) <doi:10.1086/279872>; McArdle & McDonald (1984) <doi:10.1111/j.2044-8317.1984.tb00802.x>], inference of relatedness, pedigree conversion, and simulation of multi-generational family data [Lyu et al. (2025) <doi:10.1007/s10519-025-10225-1>]. For a full overview, see [Garrison et al. (2024) <doi:10.21105/joss.06203>]. For a big data application see [Burt et al. (2025) <doi: 10.1016/j.ebiom.2025.105911>.
