artiFISHal

artiFISHal is a package of functions for the R programming language. artiFISHal is a pelagic fish community simulator, which can be used to create artificial lakes and populate them with known numbers of fish (identified in species-size groups) to mimic pelagic fish communities. artiFISHal can then be used to sample these fish with virtual acoustic and midwater trawl surveys.

Yule et al. (2013) used artiFISHal to evaluate several different approaches for estimating the biomass of pelagic fish species in the Great Lakes. An example of how to use the functions in artiFISHal is given in this vignette.


You can access the functions by installing the package from within R.

*NOTE: If you are looking for files that were used in the Great Lakes Acoustic Users Group 2014 Workshop on Trawl Performance, they are now located at the GLAUG2014 repository instead.


Thanks to Hilary Parker whose blog post Writing an R package from scratch encouraged me to create my first R package.
