Changelog for 'lsmeans' package

0.99-80 - September 19, 2012
    Now finds degrees of freedom when appropriate for all but lme objects
        (For mer objects, get df only if 'pbkrtest' installed)
    lsmeans tables now show confidence intervals instead of t tests
        and contrast output shows p values (both assuming df are available)
    Added a 'conf' argument for confidence level in lsmean intervals
    Added a 'glhargs' argument; if provided, lsmeans passes its contrasts 
        to the 'glht' function in the 'multcomp' package
    Added an 'adjust' argument for popular single-step multiplicity corrections
        (uncorrected, Tukey, Bonferroni, and Sidak)
    Contrast-generating functions now produce an 'adjust' attribute which 
        provides a default multiplicity-adjustment method
    The 'check.cells' argument is now deprecated. Instead, we do an actual 
        check of estimability in rank-deficient cases (currently can happen 
        only with 'lm' objects). This check is not optional
    Renamed the vignette to avoid confusion with the regular documentation
    Returned object is now assigned class "lsm" which has its own print method.


0.99 - August 27, 2012
    Now can handle predictors coerced to 'factor' or 'ordered'
    Now can handle predictors deleted due to rank deficiency
    Now can handle models with matrices among the predictors
        (uses 'cov.reduce' on each column; 'at' not supported for matrix covariate)
    Added support for gls objects (and documented that it works also for glm and glmer)
    Added a check for empty cells in the design (relative to the model). This (by default)
        forces a NA to be outputted for any lsmeans that are corrupted by rank deficiencies
    Generates a warning if specified factor(s) interact with other predictors
    Better and more comprehensive vignette
    Added a whole lot of comments to the code (you won't see these, but be glad,
        as it greatly aids maintainability)
    Added error messages for anticipatable user errors
    Numerous bug fixes and corrections to documentation
    Still no d.f. or P values. Those could take awhile.
    
0.90 - August 14, 2012
    First release, still needs some refinements and bullet-proofing
