cumulative returns

[tchevri]

I am so sorry to trouble - I was experiencing "issues" with Return.cumulative, so I decided to go to the sample and just ran this code:

data(managers)
Return.cumulative(managers[,1])

When I do this, I get:

Return.cumulative(managers[,1])
HAM1
Cumulative Return 3.126671

That's not what I was expecting at all.
I feel terrible - as I am sure it's something wrong on my end...
any ideas, if I may?
I made sure all my packages are up to date, and I even restarted my session.
I was expecting a history of cumulative returns.

many thanks,
thomas
