Function-function plot — ffplot • funres

Constructs a function-function (Fn-Fn) plot. That is, a plot of the average functional residual against the CDF of a U(0, 1) random variable.

Usage

ffplot(
  object,
  resolution = 101,
  n = NULL,
  ref.col = 2,
  ref.lwd = 1,
  ref.lty = "dashed",
  ...
)

# S3 method for class 'funres'
ffplot(
  object,
  resolution = 101,
  n = NULL,
  ref.col = 2,
  ref.lwd = 1,
  ref.lty = "dashed",
  ...
)

# Default S3 method
ffplot(
  object,
  resolution = 101,
  n = NULL,
  ref.col = 1,
  ref.lwd = 1,
  ref.lty = "dashed",
  ...
)

Arguments

object: Fitted model object.
resolution: Integer specifying the number of points between 0 and 1 to use. Default is 101.
n: Integer specifying the number of functional residuals to draw at random, which can help with compute time. Default is NULL which corresponds to no subsampling.
ref.col: Character string or integer specifying the color to use for the 45-degree reference line. Default is 1.
ref.lwd: Integer specifying the line width to use for the 45-degree reference line. Default is 1.
ref.lty: Character string or integer specifying the line type to use for the 45-degree reference line. Default is "dashed".
...: Additional optional arguments pass to plot().
