outliers: Identifies outliers for plot_shiny.fosr()
Description
Internal method that assigns band depth values to curves based on exact fast MBD computation (Sun & Genton, 2012).
Code modified from fbplot in fda package.
A dataframe of residuals is passed as an argument, and depths and outlying curves are returned
Usage
outliers(data, factor = 1.5)
Arguments
data
matrix or df of functional observations
factor
a constant that determines the fences for outliers. Defaults to 1.5, as in classical definition for Tukey outliers.
