Performance improvements: - Replace repeated rbind() in loops with list accumulation + bind_rows() - Cache full vector list once instead of repeated list_census_vectors() calls - Affects parent_census_vectors() and child_census_vectors() Changes: - Add testthat and microbenchmark to Suggests in DESCRIPTION - Optimize parent_census_vectors() and child_census_vectors() in R/census_vectors.R - Add comprehensive unit tests in tests/testthat/test-census_vectors.R - Add benchmark script in benchmarks/benchmark_rbind_loops.R Expected performance gains: 10-100x for deep hierarchies 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

- Fixed "API ket" → "API key" (appeared twice per message, in 3 locations) - Fixed "save is permanently in our" → "save it permanently in your" - Affected files: R/cancensus.R (lines 144, 209), R/intersect_geometry.R (line 79)
- Add retry_api_call() helper with exponential backoff for transient failures - Add format_bytes() helper for human-readable download size display - Add retry and max_retries parameters to get_census() - Report download size for data and geometry downloads when quiet=FALSE - Report number of geographic features being processed
New function that displays census vector hierarchies as an ASCII tree, helping users understand parent-child relationships between variables. Features: - Displays hierarchical structure with Unicode box-drawing characters - Supports max_depth parameter to limit tree depth - Optional show_type parameter to display Total/Male/Female types - Marks leaf nodes that have no children - Works with character vector codes or tibbles from list_census_vectors()
New features: - Add preserve_suppression_flags parameter to get_census() - When TRUE, creates _flag columns preserving original suppression codes - Codes include 'x', 'X', 'F', '...', '..', '-', 'N', '*', '**' - New census_data_quality() function for data quality analysis - Reports missing value counts and percentages per vector - Shows detailed breakdown by suppression type when flags available - Warns when missing rate exceeds threshold (default 20%) - Suggests coarser geography for better data coverage This helps users understand data suppression patterns from Statistics Canada and make informed decisions about geographic aggregation levels.
Fix API key typos in error messages
Add data quality analysis and suppression flag preservation
Add visualize_vector_hierarchy() for ASCII tree display
