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.

Examples

# Physicians' Health Study data
phs <- cbind(c(104,189),c(10933,10845)) 
rownames(phs) <- c("aspirin","placebo") 
colnames(phs) <- c("heart attack","no heart attack") 
phs 
xchisq.test(phs) 
xchisq.test(sex ~ substance, data = HELPrct)
