The RFishBC package helps fisheries scientists collect growth data from calcified structures and back-calculate estimated lengths at previous ages. The package 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 the 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 the page.
The most recent development version (on GitHub) of RFishBC may be installed by running the two lines below in your R console.
if (!require('devtools')) install.packages('devtools'); require('devtools') devtools::install_github('droglenc/RFishBC')
