A tidier version of chisq.test() for goodness of fit tests and tests of independence.
chisq_test(x, formula, response = NULL, explanatory = NULL, ...)
A data frame that can be coerced into a tibble.
A formula with the response variable on the left and the
explanatory on the right. Alternatively, a response
and explanatory
argument can be supplied.
The variable name in x

This is an alternative to using the formula

# chi-squared test of independence for college completion
# status depending on one's self-identified income class
chisq_test(gss, college ~ finrela)
# chi-squared goodness of fit test on whether self-identified
# income class follows a uniform distribution

response = finrela,

"below average" = 1/6,
"average" = 1/6,
"above average" = 1/6,
"far above average" = 1/6,
"DK" = 1/6))
