Ta. I will give that code a bash.
Could you explain why my code didn't work?

X1 X2

[1] "POSIXt" &
Normally one uses POSIXct rather than POSIXlt for storage. See R News 4/1 for

Hi Guys,
I'm cooking up my time series code. I want a data frame with first column as
timestamp in POSIXlt format.
I hit on this the problem of how to create an array/list/vector of POSIXlt
objects. Code is as follows
> dtt=array(dim = 2)
> t=as.POSIXlt( strptime("07/12/07 13:20:01", "%m/%d
