R: Initialize BM

init.simulate.BM {PhylogeneticEM} | R Documentation

## Initialize BM

### Description

Function used in `simulate` for BM initialization.

### Usage

    init.simulate.BM(phy, p, root.state, simulate_random, ...)

### Arguments

`phy` | Input tree.
`root.state` | (list) State of the root, with: random : random state (TRUE) or deterministic state (FALSE) value.root : if deterministic, value of the character at the root exp.root : if random, expectation of the character at the root var.root : if random, variance of the character at the root (pxp matrix)

### Value

paramSimu Array p x nNodes x 2 (BM), filled with NAs. Slice paramSimu[, ntaxa + 1, ] (array p x 2) is initialized with simulated states and root expectations for all the traits.
