R: Initialization for incidence matrix (full tree)

init.incidence.matrix.full {PhylogeneticEM} | R Documentation

## Initialization for incidence matrix (full tree)

### Description

`init.incidence.matrix.full` initialize the matrix updated in `update.incidence.matrix.full` for the computation of the incidence matrix of the full tree in `incidence.matrix.full`.

### Usage

    init.incidence.matrix.full(phy)

### Arguments

`phy` | Input tree.

### Details

The initialized matrix is squared of size ntaxa + nNodes. Each node represent its parental branch. A row corresponding to a tip i is initialized to a vector of zeros, with only entry i equal to one. (Branch ending at tip i is only in the i^th lineage)

### Value

Matrix of size ntaxa + nNodes.
