An 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. Several methods for this class are provided, as detailed below.
Typically, these methods just quietly do the same thing as their emmGrid
methods, using the first element of the list. You can specify which
to select a different element, or just run the corresponding emmGrid
method on object[[k]].
Usage
# S3 method for emm_list
contrast(object, ..., which = 1)
# S3 method for emm_list
pairs(x, ..., which = 1)
# S3 method for emm_list
test(object, ..., which = seq_along(object))
# S3 method for emm_list
confint(object, ..., which = seq_along(object))
# S3 method for emm_list
plot(x, ..., which = 1)
# S3 method for emm_list
coef(object, ..., which = 2)
# S3 method for emm_list
str(object, ...)
# S3 method for emm_list
summary(object, ..., which = seq_along(object))
# S3 method for emm_list
print(x, ...)
# S3 method for emm_list
as.data.frame(x, ...)
# S3 method for summary_eml
as.data.frame(x, row.names = NULL, optional = FALSE,
which, ...)Arguments
- object, x
an object of class
emm_list- ...
additional arguments passed to corresponding
emmGridmethod- which
integer vector specifying which elements to select.
- row.names, optional
Required arguments of
as.data.frame, ignored
Value
a list of objects returned by the corresponding emmGrid
method (thus, often, another emm_list object). However, if
which has length 1, the one result is not wrapped in a list.
summary.emm_list returns an object
of class summary_eml, which is a list of summary_emm
objects.
The as.data.frame methods return a single data frame via
as.data.frame(rbind(x)).
See also rbind.emm_list and as.data.frame.emmGrid
Note
The plot method uses only the first element of which; the others are ignored.
No export option is provided for printing an emm_list
(see print.emmGrid). If you wish to export these objects, you
must do so separately for each element in the list.
