pressR: Pressure Distribution Analysis for Capacitive Sensor Systems

Parse, analyze, and visualize pressure distribution data from capacitive sensor systems. Provides predefined sensor coordinate layouts for in-shoe pressure measurement, saddle pressure mapping (equine and bicycle), seating assessment, and barefoot pedography. Includes functions for peak pressure, center of pressure, pressure-time integrals, regional analysis with anatomical masks, symmetry indices, and gait cycle detection. Ships with an interactive Shiny application for data exploration and report generation.
