I am relatively new to rails and I cannot figure out what is going on here. I am using the composed_of method in an ActiveRecord class to create two aggregate properties: shipping_address and billing_address.

I am very confused about where to put the belongs_to and the has_one (and other relationship identifiers). I have read the RDoc and the agile book many times about this and I think i still see it backwards. Let me outline my app so you have an understanding... I have 2 tables: Schools { id, school_name, address_id } and Addresses { street1, street2, city, state, zip, country } *** this

Hi, I would like some extra information on the 'cgh' package in R. I noticed that there isn't much activity regarding this package on the R and BioC mailing list (I googled it). I started using this package and I have few questions: 1/ As I have a custom tiling like array @8um features resolution (affy), I have a lot of probes to work with. I'm assuming it is correct to

Victor, Me parece que podrías investigar si Scribus puede generar e insertar la salida de R en sus documentos, por lo que estás agregando a tu pregunta me parece que BI no es el camino. Si lo haces, creo que a más de uno en esta lista le interesará la experiencia. La alternativa sugerida por Emilio usando Rthml y CSS con probablemente markdown y, yo agregaría, pandoc me resulta muy interesante y

I would appreciate any solutions. I want to write formatted text file like in Fortran. More specifically with the format choice of mine for any given line (more specifics are given below).

Hello R-users I was puzzled by some strange results of an analysis and I found out what is for me a strange behaviour (I won't dare to say a bug) in both plot and points (and I suspect lines and other kind of lower level plots). If you try the following code: > data<-data.frame(dummy1=c(1:10),dummy2=c(1:10)) > plot(data$dummy1,data$dummy3) A plot of the values of dummy1 against
