Package: doBy 4.6.25

doBy: Groupwise Statistics, LSmeans, Linear Estimates, Utilities

Utility package containing: 1) Facilities for working with grouped data: 'do' something to data stratified 'by' some variables. 2) LSmeans (least-squares means), general linear estimates. 3) Restrict functions to a smaller domain. 4) Miscellaneous other utilities.

Authors:Ulrich Halekoh [aut, cph], Søren Højsgaard [aut, cre, cph]
