Workshops & Symposia
Nutrition Modeling in R is an important component of nutritional research as diet formulation is a quantitative process. To design diets that meet or exceed the nutrient requirements of the species of interest, one must be able to predict the absorbed nutrient supply and the animal needs for those nutrients, or more robustly, animal responses to the varying supply of the nutrients. Thus the construction and parameterization of models is prevalent in animal nutrition research. In the Nutrition Models Workshop, you will learn modeling approaches required to construct, parameterize, and evaluate a model.

1) Download and Install R
2) Download and Install R Studio (after install the R)
3) Tutorial: Install R packages
In RStudio, you will need to install several packages (caret, deSolve, epiR, ggplot2, lmerTest, lme4, MuMIn, plyr, reshape2). This tutorial explains how to install the packages (as well as how to install R and RStudio).
4) Download the R script and install the packages
