摘要：This is the second article in a two-part miniseries on Sweave (Leisch, 2002a), a tool that allows embedding of R code in LATEX documents so that code, results, and descriptions are presented in a consistent way. The first article (Leisch, 2002b) introduced the Sweave file format and the R functions to process it, and demonstrated how to use Sweave as a reporting tool for literate statistical practice. This article will concentrate on how to use files in Sweave format as primers or manuals for R packages, so that users have direct access to the code examples shown and so that all code can be checked automatically for syntax errors and for consistency of the usage description with the implementation.
