ref.grid-class

lsmobj-class

The codebase for lsmeans is now mostly in emmeans. These two classes
are simple extensions of the <code>emmGrid</code> class defined in emmeans,
and are provided as support for objects created in older versions of lsmeans.
For details, see <code><a rd-options="" href="/link/emmGrid-class?package=lsmeans&version=2.30-0" data-mini-rdoc="lsmeans::emmGrid-class">emmGrid-class</a></code>.

Obtain least-squares means for linear, generalized linear,
and mixed models. Compute contrasts or linear functions of
least-squares means, and comparisons of slopes.
Plots and compact letter displays. Least-squares means were proposed in
Harvey, W (1960) "Least-squares analysis of data with unequal subclass numbers",
Tech Report ARS-20-8, USDA National Agricultural Library, and discussed
further in Searle, Speed, and Milliken (1980) "Population marginal means
in the linear model: An alternative to least squares means",
The American Statistician 34(4), 216-221 <doi:10.1080/00031305.1980.10483031>.
NOTE: lsmeans now relies primarily on code in the 'emmeans' package.
'lsmeans' will be archived in the near future.
