mcmcdb_samples_flatpars-methods: Extract MCMC Samples (Flat parameter form)

In jrnold/mcmcdb: MCMC sample database classes

Description

Extract MCMC samples from an object as a a matrix of flat parameters.

Arguments

object	An object containing the MCMC samples.
flatpars	character. Flat parameters to include. If NULL, all flat parameters.
parameters	character. Parameter arrays to include. If NULL, all parameter arrays. The union of flat parameters in parameters and flatpars is included.
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
...	Options passed to internal functions.

Value

If FUN = NULL, then a matrix with columns equal to flat parameters, and rows equal to iterations. If FUN != NULL, then a list, with the results of FUN applied to each flat parameter.
