Hi Clémence,
A wild guess is that your data are not actually numeric, but factor. 
This can happen when at least one element of the data that have been 
read in cannot be coerced to a number, e.g.:

1
4
B
7
...

If you could send your data, or if too large or too confidential, a 
sample that shows the problem, we can probably offer better suggestions.
