sim.prune: Signal manipulation: prune

In davnovak/qctoy: Synthetic QC data generator

Description

Prunes signal data. Given a baseline signal, this function separates signal values into segments of size N, with respect to time. Then, from each segment, i values (1..N) are removed at random (unless j is not NULL, in which case always remove the j-th values in the given segment and disregard i). Crucially, the removed values are only set to NA, time scale stays in tact.

Usage

sim.prune(baseline, i = 1, j = NULL, N = 2, reindex = FALSE)

Arguments

baseline	baseline, as generated by function sim.baseline, possibly perturbed by other functions.
i	see description above. Defaults to 1.
j	see description above. Defaults to NULL.
N	see description above. Defaults to N.
reindex	Boolean, indicates whether time values should be re-indexed to 1..N after contraction.

Value

Modified baseline input.
