Description

Retrieve formulas from model objects

This function is primarily an internal helper function in jtools and related packages to standardize the different types of formula objects used by different types of models.

Usage

get_formula(model, ...)

## Default S3 method:
get_formula(model, ...)

## S3 method for class 'brmsfit'
get_formula(model, resp = NULL, dpar = NULL, ...)

Arguments

`model`	The fitted model object.
`...`	Ignored.
`resp`	For `brmsfit` objects, the response variable for which the formula is desired. `brmsfit` objects may have multiple formulas, so this selects a particular one. If `NULL`, the first formula is chosen (unless `dpar` is specified).
`dpar`	For `brmsfit` objects, the distributional variable for which the formula is desired. If `NULL`, no distributional parameter is used. If there are multiple responses with distributional parameters, then `resp` should be specified or else the first formula will be used by default.

Examples

data(mtcars)
fit <- lm(mpg ~ cyl, data = mtcars)
get_formula(fit)
