I have added a (very rough) first draft to the Size Structure chapter of the forthcoming Introductory Fisheries Science with R book on the book’s fishR webpage. Accompanying this chapter are major changes to all of the proportional size distribution (PSD) related functions in the FSA package —
In addition, I created a new
psdCI() function that will compute confidence intervals for PSD values using either the binomial or multinomial distributions following the flexible methodology in Brenden et al. (2008).
It is probably best to consider that all functions have changed and that your old code may be broken. In other words, carefully check your old code and the results produced by this new code (though, I also added more tests to the new code).
See the news file here for documentation of all changes.
As always, let me know if you have questions or find problems. Thanks.
