In this post on RPubs, I demonstrate how to use new functions (psdAdd() and wrAdd()) in the FSA package, along with functions in the dplyr package, to efficiently add Gabelhouse length category and relative weight variables for all species in a data.frame.  This is a follow-up to my promise in this post.

Let me know what you think.
