Dera Prof Ripley,

What did you intend there? It is not a test of no difference, but a test
that each element of the difference is not "0", and furthermore if()
expects a test of length one, not the length of nfichiers. I suspect you
intended to test length(nfichiers) > 0.
And of course, you were right.
With the condition length(nfichiers) > 0, there is no more warning.
And I tested manually length(nfichiers)>0 for different cases and it gave
the result I expected.
But still I have a problem with the save and the retrieve of tfichiers.
I keep on looking at help file and testing manually alternative scripts ...
Hoping to read you again,
