janitor (version 2.2.0)

chisq.test: Apply stats::chisq.test to a two-way tabyl

Description

This generic function overrides stats::chisq.test. If the passed table is a two-way tabyl, it runs it through janitor::chisq.test.tabyl, otherwise it just calls stats::chisq.test.

Usage

chisq.test(x, ...)

# S3 method for default chisq.test(x, y = NULL, ...)

# S3 method for tabyl chisq.test(x, tabyl_results = TRUE, ...)

Value

The result is the same as the one of stats::chisq.test. If `tabyl_results` is TRUE, the returned tables `observed`, `expected`, `residuals` and `stdres` are converted to tabyls.

Arguments

x

a two-way tabyl, a numeric vector or a factor

...

other parameters passed to stats::chisq.test

y

if x is a vector, must be another vector or factor of the same length

tabyl_results

if TRUE and x is a tabyl object, also return `observed`, `expected`, `residuals` and `stdres` as tabyl

Examples

Run this code
tab <- tabyl(mtcars, gear, cyl)
chisq.test(tab)
chisq.test(tab)$residuals
