Remove intercept(s)

Source: R/tidy_remove_intercept.R
tidy_remove_intercept.Rd

Will remove terms where var_type == "intercept".

Usage

tidy_remove_intercept(x, model = tidy_get_model(x))

Arguments

x

(data.frame)
A tidy tibble as produced by tidy_*() functions.

model

(a model object, e.g. glm)
The corresponding model, if not attached to x.

Details

If the variable column is not yet available in x, tidy_identify_variables() will be automatically applied.
