I use length(myVector),but when i want to use for example

that
function returns the number of last element,would then:
if the last position of my vector is 1440
exp(x.reconstruida[1440+1:1440+9]
So that should give you (assuming that you close the expression) a
vector of values, "e" raised to a vector from elements 1441 to 1449,
if such elements have already been defined and are numeric.
This is what I need, I hope having explained,
I do not think you have explained well enough. What is
"x.reconstruida"? Does it have a longer length than myVector?
Things would be much clearer if you made a small example (not 1440
elements long, maybe 10?).

myVector <- c(seq(10),23,35)
length(myVector)
myVector[length(myVector)]
it's unclear to me which of the two you want ...

Hello, i would like to ask you another question. Is exist
anymethod to
vectors that tells me the last element?That is to say,I have a
vector, I
want to return the position of last element. I hope having
explained.
A greeting,
