- The
`doBy`package is (yet another)`R`package with utility functions. -
`doBy`originally grew out of a need to calculate groupwise summary statistics, which explains the origin of the name:"__do__something when data is grouped__By__some variables". - The facilities for groupwise computations in
`doBy`were relatively popular in the years 2005-2010 or so. Today these facilities are less used because there are many (mostly better) alternatives. For example,`R`' s own`aggregate()`function is an alternative to`doBy`'s`summaryBy()`function. Also the dplyr package provides nice altertatives to the facilities for groupwise computations in`doBy`. - However,
`doBy`contains many other utilities. - Among these are facilities for computing LS-means (least squares means, also known as marginal means or population means).
- Development versions of
`doBy`may be available here

**Q:**- Is there a paper describing the
`doBy`package? **A:**- Not for the moment.
