For square field layouts, the package implements\ndirect common-factor constructions by first forming two\ncomponent treatment arrays, one for each factor or\nsuper-factor, and then combining them through a symbolic\ncell-wise product following Gopinath, Parsad and Mandal (2018)\n. For rectangular field\nlayouts, the package constructs designs by extracting a\nbalanced principal block from a mixed-level block design,\ntreating it as the principal column, taking the complete\ntreatment set as the principal row, and generating the full\nrow-column design by cyclic modular development. The package\nalso includes repair utilities for improving disconnected or\npartially connected row-column designs through bounded\ntreatment-swap searches while preserving the row-column layout\nstructure. The package provides diagnostic tools for\nconnectedness, orthogonal factorial structure, balance,\nestimability, and selected optimality criteria for row-column\ndesigns.", "License": "GPL-3",
