doBy: doBy - Groupwise summary statistics, LSmeans, general linear contrasts, various utilities

doBy originally contained facilities to 'do something' to data where data is partitioned 'by' some variables which define groupings of data - hence the name doBy. doBy contains a variety of utilities including: 1) Facilities for groupwise computations of summary statistics and other facilities for working with grouped data. 2) LSmeans (least-squares means), general linear contrasts. 3) Miscellaneous other utilities.
