Hello,
I need to include C (or C++)-Code in R. I'm searching for a tutorial, how to
do this. It is only a very small algorith (one function). Using google, I
read somethig about including dll-Files and so on (on windows).
Is there no possibility to include a C-File directly?!?

Hello,

The simplest interface is to use .C() in R to call the C function. The
details (with examples) are in the Writing R Extensions manual that comes
with every version of R. To compile and load the .dll/.so into R, do:
- Type R CMD SHLIB file1.c file2.c (at the command prompt, not the R
prompt)
I got it!!!
As Andy said, I generated an dll-File (using Dev-C++, it was quite easy) and
imported some R-header. This could be opened in R with dyn.load(dll-file)
und executed with .C()!!
Thanks for your help!!
PS: I've taken the Files of my (Dev C++ -)project behind:
dllmain.c:
#include
