Dear R,

I have a question for conducting a spatio-temporal inquiry, suppose I have
a time series of air temperature data for 100 years for my domain, can I
perform a inquiry like this " *How many days are there temperature above 40
degree *(CC) and get all these days", I noticed there are evolving
discussion on the space-time library, Have anyone already done this? or Any
suggestions will be appreciated.

Thanks,

Ping
