Get Last Elements of a Vector

Extract the last elements of a vector.

last(x, length.out = 1, na.rm = FALSE)

`x`	any vector.
`length.out`	integer indicating how many element are desired. If positive, return the `length.out` last elements of `x`; if negative, the last `length.out` elements are dropped.
`na.rm`	logical indicating if the last non-missing value (if any) shall be returned. By default (it is `FALSE` and) the last elements (whatever its values) are returned.

a vector of length abs(length.out) of last values from x.

This function may eventually be deprecated for the new (R 1.9.0) function tail().

Useful for the turnogram() function in package pastecs.
