packageSetup: Execute a Setup Step for a Package

Description Usage Arguments Details

View source: R/packageSetup.R

Description

The R code in one or more files is evaluated to carry out setup computations that will write some code, documentation or anything else into the source directory of an R package. Designed for package authors who want to use techniques such as the proxy classes in the XR set of interfaces, compileAttributes() in Rcpp or inline documentation in roxygen2.

Usage

1
packageSetup(file = "setup.R", dir = ".", needPackage = TRUE)

Arguments

file

The name of the files to be parsed and evaluated for the setup step, by default, "setup.R". Will look in the the current directory or the inst/tools directory for a file of this name.

dir

Optional directory to use as the working directory for the evaluation. By default the current working directory should be the source directory for the package.

needPackage

The package for which the setup is intended. Not needed if the working directory (either currently or given by dir is the source directory for that package. If supplied can be either the package name or FALSE if the setup is not intended for a package.

Details

The computations will be carried out in an environment constructed bypackageSetup() with the namespace of the package as its parent, and a .packageName object to associate it with the package. By default, the setup step looks for the DESCRIPTION file in the working directory to find the package name. The package must have been installed in the library path of this R session.
