move_units_1: move_units_1

In gtonkinhill/rhierbaps: Clustering Genetic Sequence Data Using the HierBAPS Algorithm

Description

Peform an iteration of the first move in the algorithm. That is move units from one cluster to another to improve the marginal likelihood

Usage

move_units_1(
  snp.object,
  partition,
  threshold = 1e-05,
  frac.clust.searched = 0.3,
  min.clust.size = 20,
  n.cores = 1
)

Arguments

snp.object	A snp.object containing the processed SNP data.
partition	An integer vector indicating an initial partition of the isolates.
threshold	The increase in marginal log likelihood required to accept a move.
frac.clust.searched	The percentage of a large cluster that will be moved.
min.clust.size	All isolates in clusters less than or equal to min.clus.size will be searched.
n.cores	The number of cores to use.

Value

The best partition after moving units from one cluster to another as well as a boolean value indicating whether a move increased the marginal likelihood.
