My knowledge of French is not adequate to ensure that I understand 
your question, but since I haven't seen a reply to your post, I will 
attempt a few comments.

	  Do you know the "X" matrix that generated the "Error in svd(X) : 
infinite or missing values in x"?  If yes, have you tried to find 
missing or Inf values in X?  If X is small, you could print it. 
Otherwise, you might try "which(is.na(X))" and "which(abs(X)==Inf)".

	  If you don't know the "X" in the error message, I suggest two things: 
  First, have you tried "traceback()"?  that may or may not help you. 
Second, I don't know what function you are using, but much of R is 
written in R.  I have on many occasions listed a function, copied it 
into a script file and worked through it line by line until I find the 
problem.

	  If you still have a question, feel free to try this list again.  I 
have two suggestions that may increase the speed and utility of a 
response:

	  (1) S'il vous plait, ecrire en le langue anglais.  Les lectures comme 
moi ne tienes problems avec des fautes en l'utilization de la langue. 
Et bien, il y a beaucoup de personnes qui peut repondre a un question 
posee en anglais q'en francais.

	  (2) PLEASE do read the posting guide!

	  Bon chance.
