R help - Sep 2009 - How to call R routines in C++`

Hi,
I have some results generated in my C++ program. I 'd like to call some R
functions that can test if two sample sets are from different distribution,
like Kolmogorov-Smirnov and other more sophisticated Tests. I also like to
draw the histograms of the two sample sets in the same plot using R. As a
newbie to R, I greatly appreciate any suggestions on how to call R in C/C++
and recommendations on related R packages!
Thanks and regards!
-Tim

The general approach is described in the 'R Extensions' manual and
sometimes
discussed on the r-devel list.  It is somewhat error-prone.

So have a look at 

	http://dirk.eddelbuettel.com/code/rinside.html

which very much describes your use case.  

The initial build is currently a little too hardcoded (but works out of the
box on Debian / Ubuntu in 32 and 64 bit). I need to add some more autoconf
logic to copy with slighly different directory structures on eg Fedora 64bit.

If you don't want to embed R, then Simon's Rserve is an excellent
alternative.
