fit_with: Fit a list of formulas

In tidyverse/modelr: Modelling Functions that Work with the Pipe

Fit a list of formulas

Description

fit_with() is a pipe-friendly tool that applies a list of formulas to a fitting function such as stats::lm(). The list of formulas is typically created with formulas().

Usage

fit_with(data, .f, .formulas, ...)

Arguments

data	A dataset used to fit the models.
.f	A fitting function such as stats::lm(), lme4::lmer() or rstanarm::stan_glmer().
.formulas	A list of formulas specifying a model.
...	Additional arguments passed on to .f

Details

Assumes that .f takes the formula either as first argument or as second argument if the first argument is data. Most fitting functions should fit these requirements.

Examples

# fit_with() is typically used with formulas().
disp_fits <- mtcars %>% fit_with(lm, formulas(~disp,
  additive = ~drat + cyl,
  interaction = ~drat * cyl,
  full = add_predictors(interaction, ~am, ~vs)
))

# The list of fitted models is named after the names of the list of
# formulas:
disp_fits$full

# Additional arguments are passed on to .f
mtcars %>% fit_with(glm, list(am ~ disp), family = binomial)
