Managing time series

Roofit and RooStats

Hello

Can ROOT merge two irregular time series?, as R does.
I’ve been using R for a while but it has problems with large datasets.

I know I should use some kind of database, but the packages I need (zoo and xts) don’t support it.
I’d prefer to use some application that work with large datasets transparently.

Hi,

There are no specific classes in ROOT for time series. If you can represent them as an Histogram (TH1) or a tree (TTree class), we have there method to merge them. In particular the TTree class can work with large dataset.
You would probably need to write your time series class based on a TTree,
Best Regards

Hi

Is ROOT going to add time series classes in near future?
