lfebd3 0.2.0 (2026-05-07)

Major changes

• Added support for 5-level factorial block designs.
• Added complete factorial, fractional factorial, and confounded factorial generators for 5-level designs: lfebd5(), lfebd5.fr(), and lfebd5.cf().
• Added lfebd5_analyze() for generation and analysis of 5-level factorial block designs.
• Added performance-optimized analysis for larger 5-level designs.

3-level design updates

• Added clearer 3-level function names: lfebd3(), lfebd3.fr(), lfebd3.cf(), and lfebd3.cf.full().
• Added lfebd3_analyze() as the main wrapper for 3-level designs.
• The 3-level analyzer now infers factor_levels = rep(3, n) automatically.

Output and usability changes

• Analysis functions now return classed result objects instead of printing everything directly.
• Added print methods for analysis result objects.
• Reduced unnecessary console output.
• Large 5-level outputs are limited by default when printed.

Documentation

• Added roxygen2 documentation for exported functions.
• Added small executable examples for exported functions.
