Estimated marginal means in GAMLj results

This is a convenience function to extract the estimated marginal means table from a GAMLj model. If no option is passed, extracts the emmeans table already in the model results (if any). If a formula is passed, the estimated marginal means for the defined factors are displayed.

em_means(object, formula, ...)

Arguments

object: a gamlj results object of the class `gamlj`
formula: (optional) rhs formula defining the factor(s) for which levels expected means are estimated
...: all options accepted by a gamlj model function.

Value

an object of class
