[R] A sample question

[Ambrosini Alessandro]

Hello.
Given a vector 1 3 4 2 8 9 5
I want to obtain a vector with all 0 except in the second position and in
the fifth, where the numbers are the same of the first vector.
The new vector must be
 0 3 0 0 8 0 0

Thank you very much.
Excuseme but my mind is out of order.
Alessandro
