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
compileAttributes(pkgdir = ".", verbose = getOption("verbose"))
Directory containing the package to compile attributes for (defaults to the current working directory).
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
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::wrap handlers the
compileAttributes function will also call any inline plugins available for packages listed in the
LinkingTo field of the
Returns (invisibly) a character vector with the paths to any files that were updated as a result of the call.
compileAttributes function deals only with exporting C++ functions to R. If you want the functions to additionally be publicly available from your package's namespace another step may be required. Specifically, if your package
NAMESPACE file does not use a pattern to export functions then you should add an explicit entry to
NAMESPACE for each R function you want publicly available.
In addition to exporting R bindings for C++ functions, the
compileAttributes function can also generate a direct C++ interface to the functions using the
