Rcpp (version 1.0.9)

compileAttributes: Compile Rcpp Attributes for a Package

Description

Scan the source files within a package for attributes and generate code as required. Generates the bindings required to call C++ functions from R for functions adorned with the Rcpp::export attribute.

Usage

compileAttributes(pkgdir = ".", verbose = getOption("verbose"))

Value

Returns (invisibly) a character vector with the paths to any files that were updated as a result of the call.

Arguments

pkgdir

Directory containing the package to compile attributes for (defaults to the current working directory).

verbose

TRUE to print detailed information about generated code to the console.

Details

The source files in the package directory given by pkgdir are scanned for attributes and code is generated as required based on the attributes.

For C++ functions adorned with the Rcpp::export attribute, the C++ and R source code required to bind to the function from R is generated and added (respectively) to src/RcppExports.cpp or R/RcppExports.R. Both of these files are automatically generated from scratch each time compiledAttributes is run.

In order to access the declarations for custom Rcpp::as and Rcpp::wrap handlers the compileAttributes function will also call any inline plugins available for packages listed in the LinkingTo field of the DESCRIPTION file.
