Knitr
Knitr is an R package that enables dynamic report generation by integrating R code with plain text documents, such as R Markdown, LaTeX, or HTML. It executes embedded R code chunks, captures their output (e.g., plots, tables, or text), and weaves them into a single, reproducible document. This tool is widely used in data analysis, research, and education to create documents that combine narrative, code, and results seamlessly.
Developers should learn Knitr when working in R for reproducible research, data analysis reports, or automated documentation, as it streamlines the creation of dynamic documents that update automatically when data or code changes. It is particularly useful in academic publishing, data science workflows, and teaching, where combining code execution with explanatory text enhances clarity and reproducibility.
