  data,
  fitted,
  actual,
  group = NULL,
  facet_x = NULL,
  facet_y = NULL,
  x = "fpr",
  y = "tpr",
  auc = c("title", "group"),
  size_line = 1,
  size = 11,
  env = parent.frame()
)

Arguments

actual

A character value. Evaluates to a logical or binary column.

group

A character value. Evaluates to a column.

facet_x

A character value. Evaluates to a column.

facet_y
