In cdata: Fluid Data Transformations

cdata: Fluid Data Transformations.

Description

Supplies implementations of higher order "fluid data" transforms. These transforms move data between rows and columns, are controlled by a graphical transformation specification, and have pivot and un-pivot as special cases. Large scale implementation is based on 'rquery', so should be usable on 'SQL' compliant data sources (include large systems such as 'PostgreSQL' and 'Spark'). This package introduces the idea of control table specification of data transforms (later aslo adapted from 'cdata' by 'tidyr'). A theory of fluid data transforms can be found in the following articles: https://winvector.github.io/FluidData/FluidDataReshapingWithCdata.html, https://github.com/WinVector/cdata and https://winvector.github.io/FluidData/FluidData.html.
