tf_jiggle: Make a 'tf' (more) irregular

In tf: S3 Classes and Methods for Tidy Functional Data

Make a tf (more) irregular

Description

Randomly create some irregular functional data from regular ones. jiggle it by randomly moving around its arg-values. Only for tfd. sparsify it by setting (100*dropout)% of its values to NA.

Usage

tf_jiggle(f, amount = 0.4, ...)

tf_sparsify(f, dropout = 0.5, ...)

Arguments

f	a tfd object
amount	how far away from original grid points can the new grid points lie, at most (relative to original distance to neighboring grid points). Defaults to at most 40% (0.4) of the original grid distances. Must be lower than 0.5
...	additional args for the returned tfd in tf_jiggle
dropout	how many values of f to drop, defaults to 50%.

Value

an (irregular) tfd object
