Standardizes selected measured features and averages them with declared weights. EAC is positive and EDC is inverted after scaling. This is an oxidative-oriented descriptor, not accessible capacity, a redox potential, or a universal ranking of resilience. High EDC means greater reducing capacity.
Usage
rri_capacity_index(
soil_df,
eac_col = "EAC",
edc_col = "EDC",
reactive_fe_col = NULL,
poorly_cryst_fe_col = NULL,
humic_col = NULL,
w_eac = 0.35,
w_edc = 0.25,
w_fe = 0.25,
w_humic = 0.15,
scaling = c("pnorm", "minmax", "reference"),
ref_ranges = NULL
)Arguments
- soil_df
Numeric soil measurements.
- eac_col, edc_col
Columns of electron-accepting/donating capacity.
- reactive_fe_col, poorly_cryst_fe_col
Optional Fe-pool proxy columns.
- humic_col
Optional organic redox proxy column.
- w_eac, w_edc, w_fe, w_humic
Non-negative weights.
- scaling
pnorm, minmax, or reference; pnorm is not a calibrated probability.
- ref_ranges
Named increasing finite ranges in original measurement units; mandatory for every selected column when scaling=reference.
Value
capacity_score, EAC/(EAC+EDC) ratio, contributors and observed coverage. Coverage concerns selected available columns; overlapping pools must not be mistaken for independent evidence. Common assays and reference ranges are necessary but insufficient for cross-study comparability.
Examples
df <- data.frame(EAC = c(10, 20, 30), EDC = c(5, 8, 12))
