Independent review is a valuable means of checking file quality. The review package is a tool for documenting review activity. An extension of the R programming language, it works with the Subversion version control system to create, maintain, and analyze an activity log. The log consists of records representing time-stamped version-stamped administrative acceptance of particular files by particular users. Analysis includes a report of files that need further review, because newer versions exists. This project maintains the source code for the package. Releases may be published here, and on CRAN.
