checkFF {tools}R Documentation

Check Foreign Function Calls

Description

Performs checks on calls to compiled code from R code. Currently only whether the interface functions such as .C and .Fortran are called with argument PACKAGE specified, which is highly recommended to avoid name clashes in foreign function calls.

Usage

checkFF(package, dir, file, lib.loc = NULL,
        verbose = getOption("verbose"))

Arguments

package a character string naming an installed package. If given, the installed R code of the package is checked.
dir a character string specifying the path to a package's root source directory. This should contain the subdirectory R (for R code). Only used if package is not given.
file the name of a file containing R code to be checked. Used if neither package nor dir are given.
lib.loc a character vector of directory names of R libraries, or NULL. The default value of NULL corresponds to all libraries currently known. The specified library trees are used to to search for package.
verbose a logical. If TRUE, additional diagnostics are printed.
