search for: class2

I have two objects that are associated in the following way: class Class1 < ApplicationController has_and_belongs_to_many :class2s has_and_belongs_to_many :otherClasses end class Class2 < ApplicationController has_and_belongs_to_many :class1s has_and_bleongs_to_many :otherClasses end Now, when I run the following query, @objects = Class1.find(:all, :conditions => ["class2s.id = ?", para...

...R's class(). Hadley calls this long class vector the 'implicit class' -- which is a good term but somewhat conflicting with R's (i.e. R-core's) "definition" used in the ?class help page (for ca. 11 years). R's internal C code has a nice function class R_data_class2() which computes this 'S3-dispatch-class' character (vector) for any R object, and R_data_class2() is indeed called from (the underlying C function of) R's UseMethod(). Using the above fact of an error message, I wrote a nice (quite well tested) function my.class2() which returns th...

Hi, I'm trying to understand R's object oriented abilities. I have read (in a very recent email to r-help) that R's methods package does not support private methods. However, I also looked at the source for the function "is": > is function (object, class2) { cl <- .class1(object) if (missing(class2)) return(extends(cl)) if (.identC(cl, class2) || .identC(class2, "ANY")) return(TRUE) ... The first line of the function, the assignment to cl, seems to call a function called ".class1". I was unab...

Hi, Please advice on what type of graph can be used to display the following data set. I have the following: Name Class a Class 1 a Class4 b Class2 b Class1 d Class3 d Class5 e Class4 e Class2 So each entry in name can belong to more than one class. I want to represent the data as to see where overlaps occur that is which names are in the same Class Name and also which names are uniq...

...w to R, and I have searched helpfiles and this forum on my 2 questions. Hope you guys can help me out! :-) Many thanks in advance! Cheers, Lars Q1: I imported a csv file with columnames subject and class. There are about 1000 different classes... It looks like this: subject1, class1 subject1, class2 subject2, class1 subject2, class3 ... subject999, class1 subject999, class2 Now I want to transform this in R into a table (with columnnames subject,class1,class2,...) like: subject1, yes, yes, no, ... subject2, yes, no, yes, ... ... Q2: I want to count the matching class patterns in the previous...

...data.frame is not an S4 class but is(data.frame()) finds its super-classes anyway and without the need to wrap it in asS4(). And "list' is one of the super-classes. Then is(data.frame(), "list") contradicts this. I'm not asking for a workaround. I already have one with 'class2 %in% is(object)' as reported in my original post. 'is(asS4(object), class2)' is maybe another one but, unlike the former, it's not obvious that it will behave consistently with unary is(). There could be some other surprise on the way. You're missing the point of my original po...
