Extract samples from jsdmStanFit object — extract.jsdmStanFit • jsdmstan

This function extracts named parameters from a jsdmStanFit object, with optional regular expression matching.

Usage

# S3 method for class 'jsdmStanFit'
extract(
  object,
  pars = NULL,
  permuted = FALSE,
  inc_warmup = FALSE,
  include = TRUE,
  regexp = FALSE,
  return_array = FALSE,
  ...
)

extract(object, ...)

Arguments

object: The jsdmStanFit model object
pars: A character vector of parameter names
permuted: Whether the draws should be randomly permuted, by default FALSE
inc_warmup: Whether the warmup period should be included, by default FALSE
include: Whether the parameters specified by pars should be included or excluded from the result, by default TRUE for inclusion
regexp: Whether regular expression matching should be used to match the contents of pars to the parameter names, by default FALSE
return_array: Whether to return the output as a 3 dimensional array (TRUE) or a named list (FALSE, the default)
...: Arguments passed to get_parnames()

Value

If return_array = FALSE returns a named list with each parameter group being an element of the list. Each list element is an array with the first dimension being the iteration (all chains are appended) and the other dimensions coming from the parameter dimensions. If return_array = TRUE then a 3 dimensional array is returned with the first dimension being the iterations, the second the chains and the third the parameters.
