doBy: Groupwise Statistics, LSmeans, Linear Contrasts, Utilities

Share:

The facilities can roughly be grouped as: . 1) Facilities for groupwise computations of summary statistics and other facilities for working with grouped data: 'do' something to data stratified 'by' some variables. . 2) LSmeans (least-squares means), general linear contrasts. . 3) Miscellaneous other utilities.
