Uses an S3 method to check that a given formula can be parsed based on its class. It currently scans for contrasts that are not supported and in-line functions. (e.g: lm(wt ~ as.factor(am))). Since this function is meant for function interaction, as opposed to human interaction, a successful check is silent.

acceptable_formula(model)

Arguments

model An R model object

Examples


model <- lm(mpg ~ wt, mtcars)
