R help - Nov 2003 - c code in R

Hi, my question is How i cant to execute c code within R for example
name of program probe.c (in workpath of R)
#include<stdio.h>
void main(){
int x;
scanf("%d\n",&x)
printf("%d\n",x)
}
 and in R i make 
.c("probe.c")
i'm obtain no load table simbol, but i compile the program with Borland C 
5.0 and obtain the .obj archive (probe.obj and the .exe).I have to make the 
load in R?. What is wrong?, Thanks Ruben

Your mistake was that you have read neither
a) the R for Windows FAQ, Section 7.3 "How do I include compiled C 
code?", nor
b) the manual "Writing R Extensions".

I strongly encourage you tho check this book:

The basics of S and S-Plus / Andreas Krause, Melvin Olson

It has a very detailed and easy to follow info on how to link C code with S
(which is nearly identical to R). The R documentation is certainly very
complete, but it is written for people that already has some good
knowledge. The book by Krause and Olson helped me a lot in writing some C
code for calculating fractals in R.

Hope this helps.
