mcmcdb_unflatten-method: Unflatten MCMC parameters

In jrnold/mcmcdb: MCMC sample database classes

Description

Convert parameter values from their flattened form to their original array shapes.

Arguments

x	Flattened parameter values
parameters	Object mapping flattened parameters to parameter arrays

Value

All methods return a named list of parameter arrays.

Methods

signature(x = "matrix", parameters = "function")

Each row if the matrix represents a sample interation. The returned array for a parameter array with dimension d is c(d, n), where n is the number of iterations. The function parameters should return an object of class McmcdbFlatpars.

signature(x = "matrix", parameters = "McmcdbParameters")

See method for signature(x = "matrix", parameters = "McmcdbParameters").

signature(x = "matrix", parameters = "missing")

If parameters is missing, then the default for McmcdbParameters is used.

signature(x = "McmcdbWide", parameters = "character")

The character vector parameters specifies a subset of parameter arrays to return.

signature(x = "McmcdbWide", parameters = "missing")

Uses the result of mcmcdb_parameters(x) as the parameter object.

signature(x = "numeric", parameters = "function")

The numeric vector represents a single iteration.

signature(x = "numeric", parameters = "McmcdbParameters")

See method for signature(x = "numeric", parameters = "function").

signature(x = "numeric", parameters = "missing")

See method for signature(x = "numeric", parameters = "function").
