R help - Apr 2003 - C algorithm to call R?

Does anyone have a C or C++ algorithm to call "R"? Thank you for your
help.

Hi,

I might be able to help you with that.  Check out this file from the 
Obversive project:

http://cvs.sourceforge.net/cgi-
bin/viewcvs.cgi/obversive/obversive/src/backend/Attic/RService_i.cpp?
rev=1.1.2.11&content-type=text/vnd.viewcvs-markup

The link is really long, so make sure you have everything on the above 
line.

The file you are looking at is from our RBackend component, which is a 
CORBA interface directly to the R system for running most basic code.  
I don't know what your R calling needs are specifically, but this code 
has lots of goodies you can probably use, and it is heavily commented.

The two methods to look at are RService_i::parse and 
RService_i::syntax.  In the syntax function I use a hand written 
parser I developed to return better error messages--which happens in 
the "check_syntax" method--so you can just ignore the rest.

I hope that helps.

See Chapter 4 and 5 of Writing R Extensions or

ysis+subroutines

If you want to use R functions as standalone for C then read the very
last section of Chapter 5 on building libRmath.
