[R-SIG-Finance] getSymbols is zoo or xts?

[Guillaume Yziquel]

Hello.

I'm currently wrapping up quantmod to Objective Caml using the OCaml-R 
binding I've recently been creating. It seems to be working fine, but 
I'm currently wondering things about the S3 typing of quotes retrieved 
via getSymbols.

It seems that getSymbols returns xts time series, but in the 
documentation, I only see zoo mentionned as output returned by getSymbols.

Should I assume that getSymbols returns zoo time series by default, or 
is it sytematically returning xts time series?

All the best,
