Tidy chi-squared test

A tidier version of chisq.test() for goodness of fit tests and tests of independence.

chisq_test(x, formula, response = NULL, explanatory = NULL, ...)

Arguments

x	A data frame that can be coerced into a tibble.
formula	A formula with the response variable on the left and the explanatory on the right.
response	The variable name in x that will serve as the response. This is alternative to using the formula argument.
explanatory	The variable name in x that will serve as the explanatory variable.
...	Additional arguments for chisq.test().

Examples

# chisq test for comparing number of cylinders against automatic/manual
mtcars %>%
  dplyr::mutate(cyl = factor(cyl), am = factor(am)) %>%
  chisq_test(cyl ~ am)
