emm_list
classAn emm_list
object is simply a list of
emmGrid
objects. Such a list is returned,
for example, by emmeans
with a two-sided formula or a list as its
specs
argument.
Methods for emm_list
objects include summary
,
coef
, confint
, contrast
, pairs
, plot
,
print
, and
test
. These are all the same as those methods for emmGrid
objects, with an additional which
argument (integer) to specify which
members of the list to use. The default is which = seq_along(object)
;
i.e., the method is applied to every member of the emm_list
object.
The exception is plot
, where only the which[1]
th element is
plotted.
As an example,
to summarize a single member -- say the second one -- of an emm_list
,
one may use summary(object, which = 2)
, but it is probably preferable
to directly summarize it using summary(object[[2]])
.
