knitr is an R package for literate programming and dynamic report generation, weaving code chunks from R (and other languages like Python or shell) into output documents in LaTeX, HTML, Markdown, and other markup formats. It is the engine underlying R Markdown and offers flexible chunk options, caching, and graphics device control.

Use cases

• generate reproducible reports that embed R code and results
• weave R code into LaTeX or Markdown documents
• create dynamic documents with plots and inline computed values
• build R Markdown documents with knitr as the engine
• cache expensive code chunk results in a report
• write tutorials or books mixing prose and executable code
• migrate from Sweave to a more flexible literate programming tool

When to choose

• you need reproducible research documents combining code, output, and narrative
• you use R Markdown, Quarto, or RStudio and need a weaving engine
• you want fine-grained control over chunk options, graphics devices, and output hooks
• you need to embed multiple languages (R, Python, shell) in one document

When to avoid

• you need a general-purpose static site generator without code execution
• your project does not involve R or document weaving
• you only need simple templating without code evaluation
