This is a elementary problem concerned with tests of association. You
should read up on categorical statistics, chi square tests, and general
linear models.

I have this question:
http://r.789695.n4.nabble.com/file/n4240145/data%5D.jpg
This table and data represents a sample of social housing residents in
Copenhagen and I'm asked to analyse the data with a view to seeing what
might be related to residents satisfaction levels.
And I just don't know where to start, if anyone could help this would be
greatly appreciated
Regards
Sam

Along those lines, Thompson's "R accompaniment" to Agresti's text on "Categorical Data Analysis" is simply wonderful: https://home.comcast.net/~lthompson221/SplusDiscrete.PDF It's not surprising that Agresti recommends it on the book's homepage: http://www.stat.ufl.edu/~aa/cda/cda.html However, I suspect the OP might be better off with Agresti's "An Introduction to Categorical Data Analysis (2nd ed. 2007)". So perhaps following the link on Agresti's page to the linked and website could be a first visit for worked R code examples. But when I followed that link I didn't find much that seemed appropriate for a beginner in R. Maybe looking at Friendly's website which was in the links at Bilder's site: http://www.datavis.ca/courses/grcat/ -- David.

I am having a few problems importing the data i'm running this code and the
table sets up fine but all of the data values say NA:
housdat<- c(21, 21, 28, 14, 19, 37, 34, 22, 36, 17, 23, 401, 10, 11, 36, 3,
5, 23, 61, 23, 17, 78, 46, 43, 43, 35, 40, 48, 45, 86, 26, 18, 54, 15, 25,
62)
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!

Try this: housdat<-array(housdat,dim=c(2,3,6)) Pay attention to some values that do you have inserted. Maybe you can fix it using: fix(housdat) ----- Victor Delgado cedeplar.ufmg.br P.H.D. student www.fjp.mg.gov.br reseacher -- View this message in context: http://r.789695.n4.nabble.com/Contingency-tables-example-tp4240145p4242873.html Sent from the R help mailing list archive at Nabble.com.

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').

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
