update.parsimonyCost: Actualization for parsimonyCost.
Description
update.parsimonyCost compute the line vector of a parent node, given
the vectors of its daughters.
Usage
update.parsimonyCost(daughtersParams, ...)
Arguments
daughtersParams
a (ndaughters) x (nclus) matrix with the line vectors of the cost
for the daughters node.
Value
A line vector corresponding to the parent node.
Details
This function computes the cost of putting the parent in a state k, as the
minimum number of shifts needed to get the given clustering of the trees bellow
parental node.
