wpgsd 0.3.0
New Features
-
Dunnett-type dose-finding vignette: Added new vignette demonstrating Dunnett-type group sequential design with 2 experimental arms vs. common control and 3 analyses (2 interims + final), exercising correlation computation for K > 2.
Improvements
- Completed S7 wrapper function elimination and validation refactoring.
- Organized help files into logical sections for better usability.
- Removed empty
adj-seq-p-simplified.Rmd vignette that caused UNKNOWN TITLE in pkgdown navigation.
Bug Fixes
- Fixed
generate_corr() correlation computation for K > 2 analyses: within-hypothesis and between-hypotheses loops now correctly enumerate all analysis pairs.
- Fixed S7
EventTable validator to allow single-analysis and single-hypothesis event tables (e.g., after subsetting).
- Fixed
validate_event_data_core() crash when non-numeric data is passed to floor() checks.
- Fixed inconsistent error message formatting in diagonal entry validation (
paste → paste0).
- Corrected test expectations to match actual validation error messages.
wpgsd 0.2.0
Major Features
-
S7 Class System Integration: Complete implementation of S7 classes for enhanced type safety and validation
-
EventTable class with robust validation for event data structures
-
CorrelationMatrix class with symmetry and positive definiteness validation
- Improved
generate_corr() function with S7 class support
Code Quality Improvements
Validation System Refactoring
-
Eliminated ~80% code duplication between
check_event_data(), validate_event_table_data(), and EventTable validator method through centralized validate_event_data_core() function
-
Improved validation consistency with three validation levels: “basic”, “strict”, and “s7” to support different use cases
-
Enhanced error handling with clearer, more specific error messages for validation failures
-
Relaxed Event value requirements to allow non-integer values (e.g., 100.5 events) while maintaining H1, H2, and Analysis as positive integers
S7 Class Implementation Improvements
-
Removed redundant wrapper functions
new_event_table() and new_correlation_matrix() following S7 best practices
-
Enhanced S7 class documentation with comprehensive parameter descriptions, validation details, and usage examples
-
Improved API consistency by using direct S7 class constructors (
EventTable(), CorrelationMatrix()) throughout codebase
-
Updated all examples and tests to use proper S7 constructor patterns instead of wrapper functions
Testing and Documentation Updates
-
Updated test suite to reflect validation changes and S7 constructor usage
-
Regenerated package documentation with roxygen2 to remove deprecated wrapper function documentation
-
Enhanced code maintainability through consolidated validation logic and cleaner S7 implementation
Bug Fixes and Improvements
- Fixed correlation matrix validation tolerance issues (improved numerical precision handling with 1e-12 tolerance)
- Resolved non-ASCII character issues in documentation for better portability
- Added missing
@export tags for proper function exports
- Enhanced roxygen2 documentation with clearer parameter descriptions
Documentation and Vignettes
-
Significantly improved
adj-seq-p vignette:
- Reduced code repetition by ~80% through systematic helper functions
- Enhanced readability while maintaining technical accuracy
- Added comprehensive multiplicity strategy visualization
- Improved mathematical notation and explanations
- Added proper citations (@zhao2025adjusted)
- Updated correlation calculation vignette with S7 class examples
Package Infrastructure
- Enhanced unit tests with 132+ passing test cases
- Improved package build process with better error handling
- Updated NAMESPACE with proper exports
- Enhanced pkgdown documentation site generation
