Checks if all objects are models of same class

Small helper that checks if all objects are supported (regression) model objects and of same class.

Usage

all_models_equal(..., verbose = FALSE)

all_models_same_class(..., verbose = FALSE)

Arguments

...

A list of objects.

verbose

Toggle off warnings.

Value

A logical, TRUE if x are all supported model objects of same class.

Examples

if (require("lme4")) {
  data(mtcars)
  data(sleepstudy)

  m1 <- lm(mpg ~ wt + cyl + vs, data = mtcars)
  m2 <- lm(mpg ~ wt + cyl, data = mtcars)
  m3 <- lmer(Reaction ~ Days + (1 | Subject), data = sleepstudy)
  m4 <- glm(formula = vs ~ wt, family = binomial(), data = mtcars)

  all_models_same_class(m1, m2)
  all_models_same_class(m1, m2, m3)
  all_models_same_class(m1, m4, m2, m3, verbose = TRUE)
  all_models_same_class(m1, m4, mtcars, m2, m3, verbose = TRUE)
