Obtain leastsquares means for linear, generalized linear, and mixed models. Compute contrasts or linear functions of leastsquares means, and comparisons of slopes. Plots and compact letter displays. Leastsquares means were proposed in Harvey, W (1960) "Leastsquares analysis of data with unequal subclass numbers", Tech Report ARS208, 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), 216221 <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.
