A class for modelling age / length or biomass structured populations.
FLBiol(object, ...) # S4 method for FLQuant FLBiol(object, plusgroup = dims(object)$max, ...)
The FLBiol
class is a representation of a biological fish population.
This includes information on abundances, natural mortality and fecundity.

.All slots in the class have accessor and replacement methods defined that allow retrieving and substituting individual slots.
The values passed for replacement need to be of the class of that slot. A numeric vector can also be used when replacing FLQuant slots, and the vector will be used to substitute the values in the slot, but not its other attributes.
A construction method exists for this class that can take named arguments for
any of its slots. All slots are then created to match the requirements of the
class validity. If an unnamed FLQuant
object is provided, this is used
for sizing but not stored in any slot.
