extract elements
Dear R users,
just another little question... are there other ways, I mean more easy to
write, to obtain the same result I got with:
data[95:length(dati[,1]), ]
where data is a data frame
to extract the last elements starting from a fixed position?
thank you very much
best regards

question about forward library
...#39;d want to know which inputs
are the cause of peacks in Cook's distances plot; because what I find in
abscisas axes are the steps in which some (up to 5) input data are introduced
to estimate a new LMS regression.
can someone help me?
thank you very much in advance
best regards

multiple return
...<- a+b
return (a, b, c)
}
when I call it, it runs but returns the following output:
> somma(5, 7)
$a
[1] 5
$b
[1] 7
$c
[1] 12
Warning message:
return multi-argomento sono deprecati in: return(a, b, c)
i.e. multi-return is deprecated...
thanks a lot
best regards
