I have added a very rough draft of the Recruitment chapter to the Introduction to Fisheries Analysis with R (IFAR) page.  This chapter is a complete re-working of the old Stock-Recruitment vignette and includes a section on fitting non-linear stock-recruitment functions, computing spawning potential ratio (SPR) values, and computing year-class strength indices via catch-curve residuals and two-way ANOVA models.

You should upgrade to the latest version of FSA (0.6.3) as I updated all stock-recruitment related functions (srFuns() and srStarts()).  In addition, srSims() was deleted with the main functionality put into srStarts().

I hope to submit a draft of the book to the publisher (Chapman Hall/CRC Press) by 15-Apr.  If anyone has time for a very quick review of the Recruitment chapter I would very much appreciate it (let me know though as I plan to review it myself, but will put this off a bit so as not to have mixed versions).
