infer_chisq() creates a tidy summary table for results of a chi-squared test. Alternatively, you can
select to see expected counts (type = "expected") or observed counts (type = "observed").
Usage
infer_chisq(
data,
formula,
type = c("test", "expected", "observed"),
digits = 3,
caption = NULL
)Arguments
- data
A data frame (or tibble).
- formula
The variable to run the test on, in formula syntax,
~var.- type
The kind of output to receive. Valid options are either "test" (the default), "expected", or "observed".
- digits
The number of digits to round table values to. Defaults to 3.
- caption
An override to the table caption. A sensible default is provided.
Examples
suppressWarnings(infer_chisq(mtcars, cyl~gear))
