| checkFF {tools} | R Documentation |
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.
checkFF(package, dir, file, lib.loc = NULL,
verbose = getOption("verbose"))
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 (and the result is returned invisibly). |
If the package has a namespace and if that contains a
useDynLib directive, calls in top-level functions in the
package are not reported as their symbols will be preferentially
looked up in the DLL named in the first useDynLib directive.
An object of class "checkFF", which currently is a list of the
(parsed) foreign function calls with no PACKAGE argument.
There is a print method for nicely displaying the information
contained in such objects.
This function is still experimental. Both name and interface might change in future versions.
