xchisq.test

Augmented Chi-squared test

Description

This augmented version of chisq.test() provides more verbose output.

Usage

xchisq.test(
  x,
  y = NULL,
  correct = TRUE,
  p = rep(1/length(x), length(x)),
  rescale.p = FALSE,
  simulate.p.value = FALSE,
  B = 2000,
  data = environment(x)
)

Arguments

x, y, correct, p, rescale.p, simulate.p.value, B

as in chisq.test(), but x may also be a formula, in which case x is replaced by tally(x, data) prior to the call to chisq.test().
data

a data frame for use when x is a formula.
