Normalizes values to [0,1] range using piecewise linear interpolation
between specified threshold-score pairs.
Usage
score_threshold(x, thresholds, scores)
Arguments
- x
Numeric vector of indicator values
- thresholds
Numeric vector of threshold values (must be sorted)
- scores
Numeric vector of scores corresponding to thresholds
Value
Numeric vector of scores in [0,1] range
Examples
# Custom threshold scoring for phosphorus
p_values <- c(5, 10, 15, 20, 25, 30, 35)
thresholds <- c(0, 10, 20, 30)
scores <- c(0, 0.5, 1.0, 1.0)
score_threshold(p_values, thresholds, scores)
#> [1] 0.25 0.50 0.75 1.00 1.00 1.00 1.00
