Fisheries Library in R (FLR)

Welcome to the webpage of the FLR project.

The FLR library is a collection of tools in R that facilitates the construction of bio-economic simulation models of fisheries and ecological sytems (read more). It is a generic toolbox, but is specifically suited for the construction of simulation models for evaluations of fisheries management strategies. The FLR library is under development by the FLR Team.

Software / packages

FLR is a library that consists of a number of R-packages. Each package has its own information page on the design of the classes and on the methods that are included. New packages are regularly released and several prototype packages are under development.

The basic package of FLR is FLCore that contains all the basic classes and methods to hold and manipulate the data that is needed in the simulation. The basic structure in FLCore is the FLQuant: a 5-dimensional array whereby the first dimension can be set by the users (e.g. age, length, vessel type) and the other dimensions are year, unit (e.g. sex, spawning type), season and area. Different FLQuants have been grouped into classes of FLCore.

Examples of the basic classes are the FLStock-object that holds all the information that is needed to carry out a stock assessment, and the FLFleet-object that holds the information on a fishing fleet (see: FLCore overview)

The most recent stable version of FLCore is The Golden Jackal, released: 1 February 2007. Packages are available at the repository, by calling install.packages(repos=”http://flr-project.org/R“), and through the sf.net file release system.

With the new version of R (2.5.0) we have now 2 distributions available. Be carefull with the versions of your packages.

pkg	R 2.4.1	R 2.5.0
FLCore	1.4.3	1.4.4
FLAssess	1.4.1	1.4.2
FLBayes	1.4.1	1.4.1
FLEDA	1.4.2	1.4.3
FLSTF	1.4.2	NA (check fails)
FLXSA	1.4.2	NA (check fails)

Various EU funded research-projects are contributing to the FLR platform in the form of R packages.
The core classes were developed in the FEMS project.

EFIMAS, COMMIT and other project (read more) are extending the core classes and developing secondary packages for biological and economic modelling.
