[R-SIG-Finance] [R-sig-finance] n-period return

[ehxpieterse]

Apologies if this has been asked before.

I am looking for a function to calculate the n-period return for a time
series. For example, the user would specify 11, 90 or 180 and then generate
an accompanying n-period delta.

Thanks in advance.
