..hey thanks for the answer, both of you...
but :-(, I don't seem to have an answer to my problem...
I tried with what u suggested, but it doesn't work yet...
so I will precise it...
I have a data frame...
and I would like to apply the function "prediction" which acts on two
to my data frame,I mean to all the rows of my data frame...
something like a function "Map" in Mathematica...
Shortly, I want to apply function "prediction" to a list of arguments, not
to a single argument...
I hope now it is more clear...
Thanks for the answers once more,

Not sure that was the question... If something else was meant, the
answer might be
Rephrasing the question might help...
