Hi Alan,
Take a look at the following:
> x <- 1:10
> x[length(x)]
[1] 10
> tail(x)
[1] 5 6 7 8 9 10
> tail(x, 1)
[1] 10
See ?tail for more information.

Sorry -- I meant `v(end)' and `v[length(v)]' in the first examples of
my message.

Hi,
Is there a way to specify the last element of a vector, similar to "end" in
MATLAB?
v[end]
would be MATLAB for
v(length(v))
in R.
While `v(length(v))' does yield the last element, that approach fails in the
following,
rep(v, each=2)[-c(1,length(v))]
which is meant to duplicate all
6 matches
