aquacultuR is an R package that provides functions for the calculation of growth and feed conversion metrics. The provided example datasets originate from studies in the field of aquaculture.
Until now, a comprehensive collection of equations that are commonly used in animal nutrition does not exist. This can make it difficult for people entering the field to understand how values were obtained. Also, the use of incorrect equations might not be recognized by reviewers in some cases. The advantages of wrapping those equations up in an R package in comparison to an Excel file are
- superior reproducibility
- reduced susceptibility to human errors
- having a citeable resource on hand that can be referred to
You can install aquacultuR from CRAN using:
install.packages("aquacultuR")If you prefer the latest development version, you can also install aquacultuR from GitHub by using:
require(devtools)
devtools::install_github("TellAnAx/aquacultuR")In both cases, the package can eventually be loaded using:
