get_parameters.emmGrid: Get model parameters from estimated marginal means objects

In easystats/insight: Easy Access to Model Information for Various Model Objects

Get model parameters from estimated marginal means objects

Description

Returns the coefficients from a model.

Usage

## S3 method for class 'emmGrid'
get_parameters(x, summary = FALSE, merge_parameters = FALSE, ...)

Arguments

x	A fitted model.
summary	Logical, indicates whether the full posterior samples (summary = FALSE)) or the summarized centrality indices of the posterior samples (summary = TRUE)) should be returned as estimates.
merge_parameters	Logical, if TRUE and x has multiple columns for parameter names (like emmGrid objects may have), these are merged into a single parameter column, with parameters names and values as values.
...	Currently not used.

Value

A data frame with two columns: the parameter names and the related point estimates.

Note

Note that emmGrid or emm_list objects returned by functions from emmeans have a different structure compared to usual regression models. Hence, the Parameter column does not always contain names of variables, but may rather contain values, e.g. for contrasts. See an example for pairwise comparisons below.

Examples

data(mtcars)
model <- lm(mpg ~ wt * factor(cyl), data = mtcars)

emm <- emmeans(model, "cyl")
get_parameters(emm)

emm <- emmeans(model, pairwise ~ cyl)
get_parameters(emm)
