Demystifying Knitr Package: Essential Recipes and Easy Steps for Adding Knit-Engines in R

The knitr package provides an avenue for incorporating programming languages and statistical applications into R Markdown and Quarto document for the sake of reproducibility. However, deep technical knowledge of R programming is required to achieve this task. In addition to this, the existing literature does not provide a guide on how to add econometric/statistical programs such as EViews, gretl, and Dynare. This paper develops and explains four easy steps for adding econometric/statistical applications by taking into account their peculiarities. The recipes provided in this paper can be useful in enhancing the reproducibility, accuracy, and reliability of econometric/statistical computations. The recipes can also be used in cooking new knit-engines or modifying the existing ones.
