In this post on RPubs, I demonstrate how to use new functions (
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.
