chi2.test(x, y = NULL, correct = TRUE, p = rep(1/length(x),
  length(x)), rescale.p = FALSE, simulate.p.value = FALSE, B = 2000,
  alpha = 0.05, info = TRUE)

`x`	a numeric vector or matrix. `x` and `y` can also both be factors.
`y`	a numeric vector; ignored if `x` is a matrix. If `x` is a factor, `y` should be a factor of the same length.
`correct`	a logical indicating whether to apply continuity correction when computing the test statistic for 2 by 2 tables: one half is subtracted from all \|O - E\| differences; however, the correction will not be bigger than the differences themselves. No correction is done if `simulate.p.value = TRUE`.
`p`	a vector of probabilities of the same length of `x`. An error is given if any entry of `p` is negative.
`rescale.p`	a logical scalar; if TRUE then `p` is rescaled (if necessary) to sum to 1. If `rescale.p` is FALSE, and `p` does not sum to 1, an error is given.
`simulate.p.value`	a logical indicating whether to compute p-values by Monte Carlo simulation.
`B`	an integer specifying the number of replicates used in the Monte Carlo test.
`alpha`	Standaard is `0.05`. Waarde waartegen p-waarde getoetst moet worden.
`info`	Standaard is `TRUE`. Geeft een tekstoverzicht van de analyse. Met `FALSE` wordt alleen de p-waarde geretourneerd.
