Create a reference grid from a fitted model
These functions are provided in lsmeans because they have been renamed in emmeans
ref.grid(object, ...)
recover.data(object, ...)
lsm.basis(object, ...)object |
A model object in a supported class. |
... |
Additional arguments passed to companion functions in the emmeans package. |
lsmeans now passes all its computations to emmeans, and the return values
are thus what is returned by the corresponding functions ref_grid, recover_data, and emm_basis, respectively.

fiber.lm <- lm(strength ~ machine + diameter, data = fiber)
rg <- ref.grid(fiber.lm, at = list(diameter = c(20, 24, 28)))
rg
# Note this is an emmGrid object defined in emmeans. The old "ref.grid"
# class is now an extension of this:
r.g. <- new("ref.grid", rg)
