Initialise states for SampleChains. Initialise partition state for SampleChains.

Usage

InitPartition(nodes, scorer, init_state = NULL, n_parallel_chains = 2)

Arguments

nodes: A character vector of node names.
scorer: A scorer object.
init_state: A data.frame representing a partition. Default is NULL.
n_parallel_chains: Number of parallel chains to be run in SampleChains. Default is 2.

Examples

data <- bnlearn::learning.test

scorer <- CreateScorer(
  scorer = BNLearnScorer,
  data = data
  )
InitPartition(colnames(data), scorer)
