The RFishBC package helps fisheries scientists collect measurements from calcified structures and back-calculate estimated lengths at previous ages. RFishBC is intended to replace much of the functionality provided by the now out-date fishBC software.


General desriptions for using RFishBC are under the Vignettes tab at the top of this page. I suggest at least quickly reading each vignette to get an overall feel for RFishBC and then following the workflow suggestions in the last vignette. Detailed descriptions for each function are under the Reference tab at the top of that page.
