(thanks @cedricbatailler)There are four new pairwise comparisons functions:
pairwise()pairwise_t()pairwise_bonferroni()pairwise_tukey()Each of these determines all the pairwise comparisons that can be
made for a model (fit by lm()) and then computes the
comparisons. For pairwise_t() no correction is made for
multiple comparisons, but for the others, the named correction is made.
These corrections can also be specified as arguments to the
pairwise() wrapper function. Each function produces output
that has customized printing, supports most (if not all) normal data
frame actions, and a plotting function that graphs the mean differences
and their confidence intervals.
lme4 is moved to Suggests. Models
implementing lmerMod are handled via
supernova.lmerMod and variables.lmerMod but
use of the lme4 package is limited to tests.variables()
using the new formula utility functions added. See
?formula_building, ?formula_expansion, and
?formula_extraction.equation() to extract the fitted
equation from a linear model (lm()) (thanks for the
suggestion from @ave-63!)dplyr because it changes too
quickly and has too many other dependencieslme4Extend supernova to handle within (crossed) designs

Added a NEWS.md file to track changes to the
package.
Created and added a logo to the package. (#21, @adamblake)
Added the ability to change the type of sums of squares to calculate when computing the ANOVA tables. Users can choose from 1/I/sequential, 2/II/hierarchical, 3/III/orthogonal. (#22, @adamblake)
Added pedagogical function generate_models() for
showing which models are being compared when evaluating terms in a
model. This function also supports specification of the type of sums of
squares to use. (#22, @adamblake)
Updated the README to be generated from an Rmd file and to
include information and examples regarding how to calculate different SS
types and how to use generate_models()
Added a data frame identical to Servers named Tables. This is a more appropriate name for the dataset because each row describes what happened at a table in the restaurant.
Added support for multiple regression using Type III sums of squares
Updated README for more information, examples, and a description of how the calculation of the ANOVA tables follows the model comparison approach used in Judd, McClelland, & Ryan (2017).
This version of supernova is the original distributed on CRAN. Calculation of supernova() tables with multiple predictor variables in this version will not produce output similar to the reference text, Judd, McClelland, and Ryan. However, the values for single predictor models are correct.
