Description Usage Arguments Value Author(s) See Also Examples

This function calculates the Pearsons chi-squared statistic for comparing data binned using the proBin and binByRef functions.Internally, the function utilizes the chisq.test function.

1	calcPearsonChi(ctrlRes,sampRes)

`ctrlRes`	The result generated by calling the `probBin` function on a control dataset.
`sampRes`	The result generated by calling the `byByRef` function on a sample dataset

A list containing the statistic, p.value, observed, expected counts and the residuals
