# pairwiseTestInt {pairwiseCI}

### Description

Only for internal use by pairwiseTest. Two different functions for data representable as a two numeric vectors (pairwiseTestCont) and data representable as matrix with two columns (pairwiseTestProp) as created can be done with a formula like `cbind(successes, failures) ~ group`. Functions that split up a data.frame according to one factor, and perform all pairwise comparisons and comparisons to control among the levels of the factor by calling functions that can deal with two vectors x and y or the one documented in ?Prop.test.

### Usage

pairwiseTestCont(formula, data, control=NULL, method, ...) pairwiseTestProp(formula, data, control=NULL, method, ...)

### Arguments

- formula
- a formula specifiying the response and the factor variable:
`response ~ factor` - data
- a data frame, containing the variables specified in
`formula` - method
- character string, giving the name of the function, which shall be used to calculate local p-values. Any function, taking two vectors x, and y as first arguments and returning a list with the p.value in a list element named
`p.value`can be specified. - control
- optional character string, defining the name of a control group. Must be one of the levels of the factor variable defined in
`formula`. By default control=NULL, then all pairwise comparisons between the levels of the factor variable are computed. - ...
- Arguments to be passed the function defined in
`method`

### Details

For internal use in pairwiseTest.

### Values

a data.frame containing the columns

- p.value
- numeric vector: the p.values
- compnames
- character vector: the names of the comparisons performed
- groupx
- character vector: the names of the first group
- groupy
- character vector: the names of the second group
