stanc: Translate Stan model specification to C++ code

Description

Translate Stan model specification to C++ code, which can then be compiled and loaded for sampling.

Usage

stanc(file, model_code = '', model_name = "anon_model", verbose = FALSE, ...)

Arguments

file

A character string or a connection that Rsupports specifying the Stan model specification in Stan's modeling language.

model_code

A character string either containing a Stan model specification or the name of a character string object in the workspace. This parameter is used only if parameter file is not specified, so it defaults to empty string.

model_name

A character string naming the model. The default is "anon_model". However, the model name would be derived from file or model_code (if model_code is the name of a character string object) if

verbose

TRUE print out more intermediate information during the translation procedure; FALSE otherwise. The default is FALSE.

...

optional parameters including

1. obfuscate_model_name(logical),TRUEif not specified. IfFALSE, the model name in the generated C++ code would not contain randomly generated character string so

Value

• A list with named entries:
  1. model_nameCharacter string for the model name.
  2. model_codeCharacter string for the model's Stan specification.
  3. cppcodeCharacter string for the model's C++ code.
  4. statusLogical indicating success/failure (TRUE/FALSE) of translating the Stan code.
