- Add name_pattern parameter for custom regex patterns
- Add extract_year_from_name() helper function
- Add stringr dependency for string processing
- Maintain full backward compatibility
- Add comprehensive tests and documentation
- Update vignettes and README with examples
Fixes syntax error caused by duplicate contingencyTable function definitions that would prevent R from parsing the file correctly.
- Auto-detect and handle R's automatic name modifications: * Hyphens (-) converted to dots (.) * Numeric prefixes get 'X' added - Enhanced error messages with helpful suggestions - Automatic separator adjustment with warnings - Better documentation about R name modifications - Improved user experience for edge cases
