cmapr (development version)

Major Changes

• Modernized codebase to use native R pipe (|>) instead of magrittr (%>%)
• Updated to modern purrr patterns (map() |> list_rbind() instead of map_dfr())
• Removed magrittr dependency
• Increased minimum R version to 4.1.0 (required for native pipe)

New Features

• Added cmap_example_data() function to access example data included with the package
• Added example transitions dataset for testing and demonstrations

Career Path Analysis

• Added find_career_paths() to discover promotion paths between two job titles
• Added career_ladder() to explore common progressions from a starting title

Network Analysis Integration

• Added as_igraph() to convert promotion edges to igraph objects
• Added as_tidygraph() to convert promotion edges to tidygraph objects for tidy network analysis
• Added network_summary() to calculate common network metrics (density, centrality, components, diameter)

Performance

• Major optimization of load_title_map(): Reduced load time from 23+ minutes to seconds for default usage
  • Changed default reader from “readr” to “vroom” for faster file loading
  • Changed add_features default from TRUE to FALSE to skip expensive derived columns
  • Added compute_similarity parameter (default FALSE) to make similarity computation opt-in
  • Added early sector filtering before expensive operations
  • Vectorized Jaccard similarity computation with chunked processing

Improvements

• Consolidated all globalVariables declarations in zzz.R for better maintainability
• Standardized error handling across all loader functions using cli::cli_abort()
• Added comprehensive test suite with testthat
• Added GitHub Actions workflows for CI/CD:
  • R CMD check on multiple platforms
  • pkgdown site deployment
  • Test coverage reporting

Bug Fixes

• Fixed incorrect package name reference in cmap_example_data() (was “cmaploader”, now “cmapr”)
• Resolved NAMESPACE merge conflicts

Documentation

• Improved roxygen documentation for all exported functions
