Hi all,
In my case, I just want to know what date is the lowest point in time
series.

Library(fPortfolio)
data(SWX)
data <- SWX[,"SPI"]
> class(data)
[1] "timeSeries"
attr(,"package")
[1] "timeSeries"
> min(data)
[1] 2603.37
> data[,min(data)]

It's not work for what I want.

I have ever tried "order" function. It's also not work.

how to get the data date for 2603.37 from this case ?

thank a lot.

Josh
