The Shell Game - Audit Geographic Data Transformations R package shellgame version 0.1.1 Reveals how data quality silently degrades during geographic transformations while variable labels remain unchanged. Demonstrates that transformation error is agnostic to both the variable (population, income, etc.) and the tool ('R', 'Python', etc.). Provides a reproducible audit framework for quantifying the shift from observed to imputed data at each transformation hop.
