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. |
