| FLAssess {FLAssess} | R Documentation |
FLAssess is the basic structure for age-based stock assessment. It provides a standard class for data input, diagnostic inspection and stock status estimation; either for use within a working group setting or as part of a formal Management Strategy Evaluation (MSE).
The FLAssess class can be extended to create specific implementations of assessment methods e.g. FLICA, FLSURBA, FLXSA, providing a common interface for all assessmnet methods. For example, within ICES there are two main stock assessment methods, ICA for pelagic and XSA for demersal stocks. However, differences between the methods are mainly artefacts of how they were independently developed rather than methodological. By incorporating such methods in a common class this problem will hopefully be avoided in the future.
FLAssess also incorporates methods for performing virtual population analysis (VPA) and stock projection.
In common with other FLR classes, all of the slots of the FLAssess class have accessor and replacement methods. Users are encouraged to use these instead of the @ slot accessor.
Objects can be created by calls to the methods VPA or SepVPA.
They also can be created by calls of the form
new("FLAssess", ...).
