sequence_permute: Null expectation for apparent sequences

In Sorbus-torminalis/twopointzerothree: Detects Duplicate Sequences of Offset Values

Null expectation for apparent sequences

Description

Vectors with low cardinality have a high risk of false positive duplicate sequences, especially for short sequences. sequence_permute permutes sequences and then tests for duplicates.

Usage

sequence_permute(vec, min = 5, max = 10, nsamp = 100)

Arguments

vec	vector with possible duplicates
min	minimum length of sequence sought
max	maximum length of sequence sought
nsamp	number of replications

Examples

#data from https://doi.org/10.5061/dryad.bd26mq0
TotalPrey <- c(4, 5, 4, 1, 3, 8, 2, 4, 7, 6, 1, 8, 3, 6, 2, 1, 3, 5, 2, 7,
