finalfit (version 0.8.9)

lmmixed: Mixed effects linear regression models: finalfit model wrapper

Description

Using finalfit conventions, produces mixed effects linear regression models for a set of explanatory variables against a continuous dependent.

Usage

lmmixed(.data, dependent, explanatory, random_effect)

Arguments

.data

Dataframe.

dependent

Character vector of length 1, name of depdendent variable (must be continuous vector).

explanatory

Character vector of any length: name(s) of explanatory variables.

random_effect

Character vector of length 1, name of random effect variable.

Value

A list of multivariable lme4::lmer fitted model outputs. Output is of class lmerMod.

Details

Uses lme4::lmer with finalfit modelling conventions. Output can be passed to fit2df. This is only currently set-up to take a single random effect as a random intercept. Can be updated in future to allow multiple random intercepts, random gradients and interactions on random effects if there is a need.
