[R-sig-Geo] loading all levels and time in netCDF using brick/stack

[ppanday]

Hello all

I have a netCDF file with 42 levels across time. Is it possible to load
using brick or stack both levels and time dimensions? Using brick option, I
can only load either all time or all levels? Is it possible to work with
both dimensions so that if I need to average across levels, across time, I
would be able to do that.

Thanks,
Prajjwal
