Contingency tables example
Without giving help on a potential homework problem, I would suggest that after each step you examine the object you are creating/modifying. This is a basic debugging technique that will help you out in the future. If you have a multi-step problem (as almost all are), then you may have to go step-by-step and track down when the problem is. It should be obvious where your problem is if you follow these instructions. On Thu, Dec 29, 2011 at 12:10 PM, David Winsemius

dimnames(housdat) <- list(Housing=c("Tower Block","Apartment"),
Influence=c("Low","Medium","High"),
ContactSatisfaction=c("LCLow","LCMed","LCHigh","HCLow","HCMed","HCHigh"))
ftable(housdat, row.vars=c("Housing","Influence"),
col.vars="ContactSatisfaction")
any advice would be greatly appreciated!
?Rhelp is NOT a homework help list. If you are a student, as you give every appearance of being, then you should be seeking help through your usual academic channels. This dataset regarding Copenhageners' satisfaction with housing conditions from 30 or 40 years ago is widely copied in a variety of textbooks and websites, (including R's own MASS where its name is 'housing'). -- David Winsemius, MD Heritage Laboratories West Hartford, CT
