Using `finalfit`

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

lmmixed(.data, dependent, explanatory, random_effect, ...)

.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, either, (1) name of random
intercept variable, e.g. "var1", (automatically convered to "(1 | var1)");
or, (2) the full |

... | Other arguments to pass to |

A list of multivariable `lme4::lmer`

fitted model
outputs. Output is of class `lmerMod`

.

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.
