Examples

data(bt4)
names(bt4@metiers)

# calling the FLMetier with the metier method
met <- metier(bt4,metier='TBB')
met <- metier(bt4,'TBB')

# calling the lower levels with the '[' and the '[[' levels
fl1  <- bt4['TBB']      # returns a fleet with only the 'TBB' metier
met1 <- bt4[['TBB']]    # returns the metier

fl2  <- bt4['TBB','ple'] # returns a fleet with only the 'ple' catch for 'TBB' metier
fl3  <- bt4[,'ple']      # returns a fleet with only the 'ple' catch

# possible combinations of the two include:

ca1 <-  bt4[['TBB']][['ple']] # returns the 'ple' FLCatch from metier 'TBB'
met2 <- bt4[['TBB']]['ple']   # returns the 'TBB' metier with only the 'ple' catches
