mintyr - High-Performance Phenotypic Data Pipelines for Breeding

A streamlined toolkit specifically designed for genomic selection and quantitative genetics in animal breeding. It provides high-performance data manipulation backed by 'data.table', focusing on multi-breed and multi-trait nested grouping operations. Features include zero-copy data importing, automated cross-validation splitting, and robust tools to generate and batch-export formatted phenotypic files required by various breeding software (e.g., 'ASReml-R', 'HIBLUP', 'DMU'), heavily optimizing iterative variance component analysis and large-scale evaluation pipelines.
