mcmcdb_samples_chain_parameters-methods: Extract MCMC Samples (Chains, Paramter arrays)

In jrnold/mcmcdb: MCMC sample database classes

Description

Extract MCMC samples as a list of chains, Each chain is a named list of parameter arrays.

Arguments

object	An object containing the MCMC samples.
parameters	character. Parameter arrays to include.
chain_id	integer. Chains to include. If NULL, all chains.
iter	integer. Iterations to include. If NULL, all iterations.
FUN	function Function to apply to each chain's list of parameter arrays. function(x) where x is a named list of array objects.
...	Options passed to internal functions.

Value

list. If FUN = NULL, then each element represents a chain. Each element of the chain is a named list of arrays, each array representing a parameter array and including the iterations of that parameter. If FUN != NULL, then each element is the result of FUN.
