simu_zscores: Simulation of z-scores on branches

In abichat/zazou: Z-Scores As Ornstein-Uhlenbeck

Description

Simulates z-scores

Usage

simu_zscores(tree, alphaOU, shifts = NULL, Nshifts = NULL, graph = FALSE, ...)

Arguments

tree	tree.
alphaOU	the parameter for the OU process.
shifts	vector of shifts.
Nshifts	number of shifts. Must be specified if shifts is not.
graph	show the tree, shifts and z-scores be plotted?
...	additional parameters to pass to plot_shifts().

Details

Shifts are sampled from "statistically significant values of z-scores"

Value

a vector of simulated z-scores.

Examples

set.seed(42)
tree <- ape::rcoal(5)
shift <- c(0, 0, -3, 0, 0, 0, 0, 0)
simu_zscores(tree, alphaOU = 0.2, shift = shift, graph = TRUE)
simu_zscores(tree, alphaOU = 0.2, Nshifts = 2, graph = TRUE)
