During a data analysis project it may happen that a new version of the raw data comes available or that data changes are made outside of your control. `daff` is a R package that helps to keep track of such changes. It can find differences in values between data.frames, store these differences, render them and apply them as a patch to a new data.frame. It can also merge two versions of a data.frame having a common parent version. It wraps the daff.js library of Paul Fitzpatrick (http://github.com/paulfitz/daff) using the V8 package.
