simple problem

Hello,

I have a little problem, very simple, but i can't solve it.

I have a list of files
I have a function

I want that the function take files one to one
(the results is a matrix (1 file (the values) for 1 column))

I used some functions (like apply, lapply and more)

but in each case,
i have a warning message : "only first element of `description' argument 
used "
it takes only the first file...

if someone have an idea

Thanks  a lot
