to a bug in version 1.4joint_tests(), we changed the default from
cov.reduce = range to cov.reduce = meanint,
where meanint(x) returns mean(x) + c(-1, 1).
This centers the covariate values around their means, rather than their
midranges, and is more in line with the default of
ref_grid(..., cov.reduce = mean). However, this change in
default will change the results of joint_tests() from past
experiences with models having covariates that interact with factors or
other covariates. We also added a section on covariates to the help for
joint_tests(), and added another function
symmint() for use in cov.reduce.print.summary_emm() now puts by groups in
correct order rather than in order of appearance.as.data.frame method has a new argument
destroy.annotations, which defaults to FALSE –
in which case it returns a summary_emm object (which

wrap their results in as.data.frame because they want to
access displayed results in later steps. But in doing so they have
missed potentially useful annotations. Users who have used
as.data.frame to see results with lots of digits should
instead use emm_options(opt.digits = FALSE).>= 4.1.0, allowing freedom

added hidden emm_list support to several functions like
add_grouping(), emmip(), and
emmeans() itself. These changes, we hope, help in
situations where users create objects like
emm <- emmeans(model, pairwise ~ treatment) but are not
experienced or attuned to the distinction between emmGrid
and emm_list objects. The mechanism for this is to provide
a default of for which element of the emm_list to use. A
message is shown that specifies which element was selected and
encourages the user to specify it explicitly in the future via either
[[ ]] or a which argument; for example,
plot(emm[[1]]) or plot(emm, which = 1).joint_tests() and
test(..., joint = TRUE) now has an "est.fcns"

ref_grid()) to limit the number of rows in the reference

used to work – but only in fairly extreme situations. Some
users report extreme performance issues that can be traced to the size
of the reference grid being in the billions, causing memory to be paged,
etc. So providing this limit really is necessary. The default is 10,000
rows. I hope that most existing users don’t bump up against that too
often. The nuisance (or non.nuisance) argument
in ref_grid() (see below) can help work around this
limit.nuisance option in ref_grid(), by
which we can specify names of factors to exclude from the reference grid
(accommodating them by averaging) (#282, #292). These must be factors
that don’t interact with anything, even other nuisance factors. This
