R how to extract the date after using xts package apply.weekly

Question

I used the apply.weekly function but can not figure out how to get the actual dates the output of my object x looks like

           [,1]
2012-12-02    2
2012-12-09    9
2012-12-10   10

I've tried rownames(x) etc but can't extract out the dates as a vector

Answer 1

index(x) #gives you the date required
