%description
Constructs and analyzes optimal row-column designs for mixed-level
factorial experiments under square and rectangular field layouts. For
square field layouts, the package implements direct common-factor
constructions by first forming two component treatment arrays, one for
each factor or super-factor, and then combining them through a symbolic
cell-wise product following Gopinath, Parsad and Mandal (2018)
<doi:10.1080/03610926.2017.1376091>. For rectangular field layouts, the
package constructs designs by extracting a balanced principal block from a
mixed-level block design, treating it as the principal column, taking the
complete treatment set as the principal row, and generating the full
row-column design by cyclic modular development. The package also includes
repair utilities for improving disconnected or partially connected
row-column designs through bounded treatment-swap searches while
preserving the row-column layout structure. The package provides
diagnostic tools for connectedness, orthogonal factorial structure,
balance, estimability, and selected optimality criteria for row-column
designs.
