Examples



 # Create a data frame with admissions data
 Admit <- factor(c(rep('Admitted', 46), rep('Rejected', 668)))
 Gender <- factor(c(rep('M', 22), rep('F', 24), rep('M', 351), rep('F', 317)))
 Admissions <- data.frame(Admit, Gender)

 # For most efficient computations, return an xtabs object from rxCrossTabs
 adminXtabs <- rxCrossTabs(~Admit:Gender, data = Admissions, returnXtabs = TRUE)
 rxChiSquaredTest(adminXtabs)
 rxFisherTest(adminXtabs)
 rxKendallCor(adminXtabs, type = "b")
