lme4_to_glmmr: Map lme4 formula to glmmrBase formula

In glmmrBase: Generalised Linear Mixed Models in R

Map lme4 formula to glmmrBase formula

Description

Returns a formula that can be used for glmmrBase Models from an lme4 input.

Usage

lme4_to_glmmr(formula, cnames)

Arguments

formula	A lme4 style formula
cnames	The column names of the data to be used. These are used to check if the specified clustering variables are in the data.

Details

The package lme4 uses a syntax to specify random effects as '(1|x)' where 'x' is the grouping variable. This function will modify such a formula, including those with nesting and crossing operators '/' and ':' into the glmmrBase syntax using the 'gr()' function. Not typically required by the user as it is used internally in the 'mcml_lmer' and 'mcml_glmer' functions.

Value

A formula.

Examples

df <- data.frame(cl = 1:3, t = 4:6)
f1 <- lme4_to_glmmr(y ~ x + (1|cl/t),colnames(df))
