analyze_water_quality_comprehensive: Analyze water quality comprehensively with flexible data handling

Description

Complete water quality analysis with flexible data input handling, robust error checking, and comprehensive spatial integration. Supports any water quality dataset format with automatic column detection and standardized processing.

Usage

analyze_water_quality_comprehensive(
  water_data,
  variable = NULL,
  region_boundary = NULL,
  river_network = NULL,
  output_folder = tempdir(),
  thresholds = NULL,
  coord_cols = NULL,
  date_column = NULL,
  station_id_col = NULL,
  quality_filters = list(),
  verbose = FALSE
)

Value

List with comprehensive water quality analysis results:

• water_data: Processed spatial data

• statistics: Summary statistics by variable and category

• spatial_analysis: Spatial pattern analysis

• temporal_analysis: Temporal trends (if date data available)

• threshold_analysis: Threshold exceedance analysis

• output_files: Paths to generated output files

• metadata: Analysis metadata and parameters

Arguments

• File path (CSV, shapefile, GeoJSON)

• data.frame with coordinates

• sf object

• List of datasets for multi-dataset analysis

variable

Variable to analyze (auto-detected if NULL)

region_boundary

Region boundary (optional)

river_network

Optional river network data for context

thresholds

Named list of threshold values for classification (optional)

coord_cols

Coordinate column names (auto-detected if NULL)

date_column

station_id_col

Station ID column name (auto-detected if NULL)

quality_filters

Quality control filters to apply

verbose

Print detailed progress messages

Examples

if (FALSE) {
# These examples require external data files not included with the package
# Flexible data input - auto-detects columns
results <- analyze_water_quality_comprehensive("water_stations.csv")

# Specify parameters for custom data

  water_data = my_data,
  variable = "nitrate_concentration",
  region_boundary = "Ohio",
  coord_cols = c("longitude", "latitude"),
  thresholds = list(
    Normal = c(0, 2),
    Elevated = c(2, 5),
    High = c(5, 10),
    Critical = c(10, Inf)
  )
)

# Multi-dataset analysis
results <- analyze_water_quality_comprehensive(
  water_data = list(
    surface = "surface_water.csv",
    groundwater = "groundwater.csv"
  ),
  variable = "total_nitrogen"
