Example datasets for the classes defined in FLCore.

Details

  • ple4, FLStockA dataset for North Sea (ICES Area IV) plaice. Catch, landings, discards, natural mortality, weight-at-age and maturity, together with the VPA estimated abundances and fishing mortalities.

  • ple4sex, FLStockA dataset of North Sea (ICES Area IV) plaice disaggregated by sex. Catch, yield, landings, discards, natural mortality, weight-at-age and maturity, together with the VPA estimated abundances and fishing mortalities.

  • ple4.index, FLIndexA dataset of North Sea (ICES Area IV) plaice survey catch per unit effort, index and index variance.

  • ple4.indices, FLIndicesA dataset of three North Sea (ICES Area IV) plaice survey catch per unit effort series. Index and index variance.

  • ple4.biol, FLBiolA dataset of the North Sea plaice population. Numbers, natural mortality, mass and fecundity-at-age.

  • nsher , FLSRStock and recruit data and fitted relationship for autumn spawning North Sea herring.

Datasets can be loaded by issuing the data command, like in data(ple4).
