# 80_CALCULATE_KPIS.R (CONSOLIDATED KPI CALCULATION)
|
|
# ============================================================================
|
|
# UNIFIED KPI CALCULATION SCRIPT
|
|
#
|
|
# This script combines:
|
|
# 1. Per-field weekly analysis (from 09c: field-level trends, phases, statuses)
|
|
# 2. Farm-level KPI metrics (from old 09: 6 high-level indicators)
|
|
#
|
|
# FEATURES:
|
|
# - Per-field analysis with SC-64 enhancements (4-week trends, CI percentiles, etc.)
|
|
# - Farm-level KPI calculation (6 metrics for executive overview)
|
|
# - Parallel processing (tile-aware, 1000+ fields supported)
|
|
# - Comprehensive Excel + RDS + CSV exports (21 columns per spec)
|
|
# - Test mode for development
|
|
|
|
# CRITICAL INTEGRATIONS:
|
|
#
|
|
# 1. IMMINENT_PROB FROM HARVEST MODEL (MODEL_307)
|
|
# [✓] Load script 31 output: {project}_week_{WW}_{YYYY}.csv
|
|
# Columns: field, imminent_prob, detected_prob, week, year
|
|
# [✓] LEFT JOIN to field_analysis_df by field
|
|
# [✓] Use actual harvest probability data instead of placeholder
|
|
#
|
|
# 2. AGE FROM HARVEST.XLSX (SCRIPTS 22 & 23)
|
|
# [✓] Load harvest.xlsx with planting_date (season_start)
|
|
# [✓] Extract planting dates per field
|
|
# [✓] Calculate Age_week = difftime(report_date, planting_date, units="weeks")
|
|
#
|
|
# COMMAND-LINE USAGE:
|
|
# Option 1: Rscript 80_calculate_kpis.R 2026-01-14 angata
|
|
# Arguments: [end_date] [project_dir]
|
|
#
|
|
# Option 2: Rscript 80_calculate_kpis.R 2026-01-14 angata 7
|
|
# Arguments: [end_date] [project_dir] [offset_days]
|
|
#
|
|
# & "C:\Program Files\R\R-4.4.3\bin\x64\Rscript.exe" r_app/80_calculate_kpis.R 2026-01-12 angata 7
|

# Usage in run_full_pipeline.R:

# main()
|
|
|
|
# ============================================================================
|
|
# NEXT INTEGRATIONS (See Linear issues for detailed requirements)
|
|
# ============================================================================
|
|
# 1. [✓] Load imminent_prob from script 31 (week_WW_YYYY.csv)
|
|
# 2. [✓] Load planting_date from harvest.xlsx for field-specific age calculation
|
|
# 3. [ ] Improve Status_trigger logic to use actual imminent_prob values
