last n entries of an OrderedCollection

wondering of there is a built in function to spit out the last n
entires of an ordered collection..
in a pinch, this worked:
| ipcount newList |
ipcount := self repository size.
newList := OrderedCollection new.
(ipcount - anInteger) to: ipcount do: [ :n | newList add: (self
repository at: n) ].

but i am guessing that is a total kludge...
thanks!

Use #last: e.g.,

        collection := (1 to: 50) asOrderedCollection.
        collection last: 5.            "45 .. 50"

There is also #first: and the companions #allButFirst: and #allButLast:,
e.g.,

        collection first: 5.           "1 .. 5"
        collection allButFirst: 5.     "6 .. 50"
        collection allButLast: 5.      "1 .. 45"

And of course these work with strings too, thus:

        'image.bmp' last: 4. ".bmp"
        'image.bmp' allButLast: 4. "image"

i take that back...

looking again, the reason i didn't see that was because it's inherited
from SequenceableCollection..

next time i go looking for functions, i will look up the hierarchy if
i don't immediately see it..

thanks again..
