Friedrich Leisch in 2002.
The purpose is "to create dynamic reports, which can be updated automatically if data or analysis change".
The data analysis is performed at the moment of writing the report, or more exactly, at the moment of compiling the Sweave code with Sweave (i.e., essentially with R) and subsequently with

. This can facilitate the creation of up-to-date reports for the author.
Because the Sweave files together with any external R files that might be sourced from them and the data files contain all the information necessary to trace back all steps of the data analyses, Sweave also has the potential to make research more transparent and reproducible to others.
However, this is only the case to the extent that the author makes the data and the R and Sweave code available. If the author only publishes the resulting
