Dear Phil,
Thanks for your reply.
 
I tried using:
 
But this message appears:
 
Error in scale(newdata[, object$scaled, drop = FALSE], center = object$x.scale$"scaled:center",  : 
  (subscript) logical subscript too long
 
I also changed the separator but did not solve the problem
 
many thanks,
Nancy
