15, 25,

housdat<-array(dim=c(2,3,6))
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').
