rxPairwiseCrossTab: Apply Function to Pairwise Combinations of an xtabs Object

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

                       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)
