ROC Plot

Source: R/skill_ROCPlot.R

This function plots ROC curves for a variety of observed classification thresholds.

skill_ROCPlot(
  predicted,
  observed,
  t1Range = c(0, 100),
  t2s = seq(10, 100, 10),
  n = 101,
  colors = grDevices::rainbow(length(t2s))
)

Arguments

predicted

vector of predicted values (or a ws_monitor object with a single location)
observed

vector of observed values (or a ws_monitor object with a single location)
t1Range

lo and high values used to generate test thresholds for classifying predicted data
t2s

vector of thresholds used to classify observed data
n

number of test thresholds in ROC curve
colors

vector of colors used when plotting curves
