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

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

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 |

explanatory | The variable name in |

... | Additional arguments for chisq.test(). |
