FLQuants is a list of FLQuant objects. It is very
similar to the standard list class. It implements a lock mechanism
that, when turned on, does not allow the user to increase or decrease the
object length. The elements of FLQuants must all be of class
FLQuant.
Usage
FLQuants(object, ...)
# S4 method for ANY
FLQuants(object, ...)
# S4 method for FLComp
FLQuants(object, ...)
# S4 method for missing
FLQuants(object, ...)
# S4 method for list
FLQuants(object, ...)
# S4 method for FLQuants
FLQuants(object, ...)Slots

Examples
# Compute various FLStock indicators
data(ple4)
fqs <- FLQuants(ssb=ssb(ple4), catch=catch(ple4), rec=rec(ple4),
f=fbar(ple4))
