Plot Method for Outliergram Objects

Source: R/outliers.R
plot.outliergram.Rd

Creates a scatter plot of MEI vs MBD with the parabolic boundary and identified outliers highlighted.

Usage

# S3 method for class 'outliergram'
plot(
  x,
  col_normal = "gray60",
  col_outlier = "red",
  color_by_type = FALSE,
  show_parabola = TRUE,
  show_threshold = TRUE,
  label = "index",
  label_all = FALSE,
  ...
)

Arguments

x

An object of class 'outliergram'.

col_normal

Color for normal observations. Default is "gray60".

col_outlier

Color for outliers (used when color_by_type = FALSE). Default is "red".

color_by_type

Logical. If TRUE, color outliers by their type (shape, magnitude_high, magnitude_low, mixed). Default is FALSE.

show_parabola

Logical. If TRUE, draw the theoretical parabola. Default TRUE.

show_threshold

Logical. If TRUE, draw the adjusted threshold parabola. Default TRUE.

label

What to use for labeling outlier points. Options:

  • "index": Use numeric indices (default)

  • "id": Use observation IDs from the fdata object

  • A column name from the fdata metadata (e.g., "patient_id")

label_all

Logical. If TRUE, label all points, not just outliers. Default FALSE.
