data(mydata)
mydata.sumscore <- rowSums(mydata[,c("item1", "item2", "item3", "item4")])
meanTable(mydata.sumscore, mydata$age_group7)
meanTable(mydata.sumscore, mydata$age_group7, mydata$sex)
meanTable(mydata.sumscore, mydata$sex, mydata$age_group7)
(tab <- meanTable(mydata.sumscore, mydata$age_group7, mydata$sex, variation="sd"))

#saveTable(tab, "meanTable.rtf")
