Array to xts/zoo

Hi,

I have an array which holds the cumulative profit of a trading strategy over
time. I use raw data of class xts/zoo by using quantmod's
getSymbols("^DJI").

My question: How do I transform my array to a zoo/xts class, by also using
the date formatting in the raw data? The array shows the corresponding
profit/loss for each day of data downloaded. Both my array and the raw data
from getSymbols have the same number of elements.

Thanks in advance.

failing that, try cbind()

In the future, I suggest that when dealing with timeseries, keep *all* 
of your data conveniently indexed by time.

Cheers,
