Description

Apply a function 'FUN' to all pairwise combinations of the rows and columns of an xtabs object, stratifying by higher dimensions.

Usage

  rxPairwiseCrossTab(x, pooled = TRUE, FUN = rxRiskRatio, ...)
 ## S3 method for class `rxPairwiseCrossTabList':
print  (x, ...)
 ## S3 method for class `rxPairwiseCrossTabTable':
print  (x, digits = 3, scientific = FALSE, p.value.digits = 3, ...)

Arguments

`x`

an object of class xtabs, rxCrossTabs, or rxCube for rxPairwiseCrossTab. An object of class rxPairwiseCrossTabList or rxPairwiseCrossTabTable for the print methods of rxPairwiseCrossTabList and rxPairwiseCrossTabTable objects.

`pooled`

logical value. If TRUE, the comparison groups are pooled. Otherwise all pairwise comparisons are included.

`FUN`

function that takes a two by two table and returns an object of class htest.

`...`

additional arguments.

`digits`

number of digits to use in printing numeric values.

`scientific`

logical value. If TRUE, scientific notation is used to prin tnumeric values.

`p.value.digits`

number of digits to use in printing p-values.

Value

a rxPairwiseCrossTabList object.

 mtcarsDF <- rxFactors(datasets::mtcars, factorInfo = c("gear", "cyl", "vs"), 
                       varsToKeep = c("gear", "cyl", "vs"), sortLevels = TRUE)
 xtabObj <- rxCrossTabs(~ gear : cyl : vs, data = mtcarsDF, returnXtabs = TRUE)

 rxPairwiseCrossTab(xtabObj, FUN = rxRiskRatio)
 rxPairwiseCrossTab(xtabObj, pooled = FALSE, FUN = rxOddsRatio)
