Thanks, that was a stupid mistake (I did not know that this is so
important).
So I still have a problem realy more complex and I do not know was is
wrong. I am running a .C procedure in a R loop.
After 4, 5 or sometimes 6 call to the C procedure, Rgui crash (it closes
asking me if I want to send a report to Microsoft).
Is there a debuger that can run the C code with some R in it ? And what
kind of mistake can provoque such a crash ?
Thanks
Christophe
So I thaught that I find t

Hi the list,
I need to include some C code in R, but the behavior of the C code is
strange : Here is my code :
--- 8< ---
Rprintf("\n XXXX mTraj=%f
mClus=%f",mTraj[i+nbId*c],mClustersCenter[j+nbClusters*c]);
Rprintf("\nDistA=%d Tmp=%d",dist,tmp);
tmp = mTraj[i+nbId* c] - mClustersCenter [j+nbClusters* c];
Rprintf("\nDistB=%d Tmp=%d",dist,tmp);
dist += (tmp * tmp);
Rprintf("\nDistC=%d Tmp=%d",dist,tmp);
--- 8< ----
Herer are the stranges results it gives :
XXXX mTraj=1.000000 mClus=3.000000
DistA=0 Tmp=0
DistB=0 Tmp=0
DistC=0 Tmp=1074790400
I ask on a C chat, but no one can answer me.
Any idea of what wrong ?
You likely have the wrong types for the variables you're printing. In
C, the format has to match the type of the variable; if you use the
wrong one, you get garbage.
