How do you mean "embed"? Sorry for naivity on this, but I've only done that within Gnome so far. Just a link would be fine.
See http://developer.r-project.org/embedded.html NEWS says o Preliminary support for building R as a shared library (`libR') under Unix. Use configure with option `--enable-R-shlib' or do `make libR' in directory `src/main' to create the shared library. There is also a linker front-end `R CMD LINK' which is useful for creating executable programs linked against the R shared library. and that's about all there is. The idea is that you can make a shared library version of R. libR.so, and link your application against it. There are even some examples, but I don't know of a link to those.
The RlibTest link in
http://www.omegahat.org/download/R/other/
will give you some code that Kurt H. and I used to check
all was well with the linking against libR.so and also provide
some basic examples.
More comprehensive examples are in the different Omegahat packages
such as the RSPython, RSPerl( and more recently from the CVS tree in
the R module under Apache.)
