|(require sawzall)||package: sawzall-lib|
Sawzall is a grammar for manipulating data, and provides a set of primitives that allow solving common data-manipulation problems in a style similar to spreadsheets. Sawzall uses the data-frame library as its primary object of input and output, and is designed to manipulate these data-frames.
Sawzall is designed around tidy data, but most data found in the wild will not be tidy. For more information, see Pivoting.
