Plot Receiver Operating Characteristic (ROC) curve for metabolites with or without covariates

Usage

plot_ROC(
  object = NULL,
  y = NULL,
  x = NULL,
  model_a = NULL,
  model_b = NULL,
  lab = NULL,
  text_x = 0.6,
  text_y = 0.3
)

object: A Metabolite object.
y: A column name for the disease (0, 1)
x: One variable name (if x is provided, model_a and model_b should be NULL or vice versa).
model_a: Column names for model a (one or more covariates, as the first model).
model_b: Column names for model b (one or more covariates, as the second model).
lab: Title (eg. "BIOCHEMICAL"), default value is x.
text_x: Annotation position of text in x-axis.
text_y: Annotation position of text in y-axis.
