R bindings for DynCall.

Description

This package provides an R interface to call C/C++ and Fortran functions from shared libraries.

The foreign function interface in R (functions such as .C and .Call) is limited in several ways. You can not establish function calls to typical C functions available on the net today. This package claims to allow a much broader integration with

In R, one can call foreign functions through .C, .Call, .Call.Graphics and .ExternalCalling a foreign function in is available using .C, .Call, .External The abilities of R to call precompiled code are limited to R designed languages.

In further provides several utilities to easy the integration with compiled code to shrink the amount of glue code required to connect R with code from C/C++, Fortran etc.

The package is based on dyncall, a C library, that provides a foreign function call interface and has been ported to a large number of platforms. See http://dyncall.org for a list of platforms included.

Function overview of rdyncall:

• Load shared libraries. See dynload.
• Resolving symbolic names to function pointers. See dynload.
• Call foreign functions with support for multiple calling conventions. See dyncall.
• Make R functions callable from C context transparently. See callback.
• Dynamic binding of shared library functions through text-based type signatures. See dyncall and dynbind signatures.
• Integration of shared libraries using dynamic binding informations. See dynport.
