valueInCompiledNimbleFunction

get or set value of member data from a compiled nimbleFunction using a multi-interface

Description

Most nimbleFunctions written for direct user interaction allow standard R-object-like access to member data using $ or `[[`. However, sometimes compiled nimbleFunctions contained within other compiled nimbleFunctions are interfaced with a light-weight system called a multi-interface. valueInCompiledNimbleFunction provides a way to get or set values in such cases.

Usage

valueInCompiledNimbleFunction(cnf, name, value)

Arguments

`cnf`	Compiled nimbleFunction object
`name`	Name of the member data
`value`	If provided, the value to assign to the member data. If omitted, the value of the member data is returned.

Details

The member data of a nimbleFunction are the objects created in setup code that are used in run code or other member functions.

Whether multi-interfaces are used for nested nimbleFunctions is controlled by the buildInterfacesForCompiledNestedNimbleFunctions option in nimbleOptions.

To see an example of a multi-interface, see samplerFunctions in a compiled MCMC interface object.
