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

2013-01-08 Thread 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
