Pedigree Functions R package kinship2 version 1.9.6.2 CRAN Task View: Agriculture (https://CRAN.R-project.org/view=Agriculture) CRAN Task View: MixedModels (https://CRAN.R-project.org/view=MixedModels) Routines to handle family data with a pedigree object. The initial purpose was to create correlation structures that describe family relationships such as kinship and identity-by-descent, which can be used to model family data in mixed effects models, such as in the coxme function. Also includes a tool for pedigree drawing which is focused on producing compact layouts without intervention. Recent additions include utilities to trim the pedigree object with various criteria, and kinship for the X chromosome.
