[R] Call R program from C++ code

[Kisas]

Hi Vladimir:
	Thank you very much! I'm very interested in this sentence: " R can
be compiled as a shared library object, that you can dynamically load from
your application and use its functions." That's would be great if R programs
can be "compiled" as shared library object(.lib? or .dll ? ) Can you please
give more details about that? 

Best,
Feng

"Writing R Extensions" manual contains chapters dedicated to parsing and
evaluating of the R extensions from C.
Also, I vaguely remember I've seen something like "Embedding R" somewhere in
manuals.
R can be compiled as a shared library object, that you can dynamically load
from your application and use its functions.
R doesn't have a compiler, it's the interpreted language. 
However, it can parse a character string representing an expresstion and
transform it into the internal form, ready for evaluation.
