Difference in means and proportions
Wrappers around diff(mean(...)) and diff(prop(...)) that
facilitate better naming of the result
diffmean(x, ..., data = parent.frame(), only.2 = TRUE) diffprop(x, ..., data = parent.frame(), only.2 = TRUE)
if (require(mosaicData)) {
diffprop( homeless ~ sex , data=HELPrct)
do(3) * diffprop( homeless ~ shuffle(sex) , data=HELPrct)
diffmean( age ~ substance, data=HELPrct, only.2=FALSE)
do(3) * diffmean(age ~ shuffle(substance), data=HELPrct, only.2=FALSE)
diffmean( age ~ sex, data=HELPrct)
do(3) * diffmean(age ~ shuffle(sex), data=HELPrct)
