daff {daff}

Data diff, patch and merge for R

Description

Daff calculates differences between two data.frames. This difference can be stored and later used to patch the original data. Differences can also be made visual by using render_diff showing what changed.

Details

Storing the difference between data sets allows for tracking or incorporating manual changes to data sets. Ideally changes to data should be scripted to be reproducable, but there are situations or scenario's where this is not possible or happens out of your control. daff can help track these changes.

actions

diff_data	Find differences in values between data.frames
patch_data	Apply a patch generated with diff_data to a data.frame
merge_data	Merge two diverged data.frames orginating from a same parent
