R: Update formula in the general case

update.partitionsNumber.gen {PhylogeneticEM} | R Documentation

## Update formula in the general case

### Description

`update.partitionsNumber.gen` apply the actualization formula to get Nk and Ak of a node given its daughters.

### Usage

    update.partitionsNumber.gen(daughtersParams, ...)

### Arguments

`daughtersParams` | : matrix with 2*npart columns. Each row contains the result of partitionsNumber for the children of a given node

### Details

Uses functions `sum.partitions` and `sum.simplex` to compute the needed sums.

### Value

vector of size 2*npart. For k=1:npart it contains the number of partitions with k groups compatible with the sub tree starting at the current node ; and for k=(npart+1):2*npart, it contains the number of "marked" partitions with (k-npart) groups compatible with the sub tree starting at the current node.
