search for: class2s

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 = ?", param...

Dear Martin, What's the ETA for _R_CLASS_MATRIX_ARRAY_=TRUE to become the new unconditional behavior in R devel? Thanks! H.

TLDR: This is quite technical, still somewhat important: 1) R 4.0.0 will become a bit more coherent: a matrix is an array 2) Your package (or one you use) may be affected. >>>>> Martin Maechler >>>>> on Fri, 15 Nov 2019 17:31:15 +0100 writes: >>>>> Pages, Herve >>>>> on Thu, 14 Nov 2019 19:13:47 +0000 writes:

Hi, Let''s say: class Class2 << ActiveRecord belongs_to: class1 end class Class1 << ActiveRecord has_many :class2s def get_max_class2 ?how to get the max of class2 list ? end end I would like to know how I have to write the get_max_class2 method in order to have the max value of the class2 list ? I would like to call this method this way: class2_max = class1.get_max_class2 Any ideas ? Thanks...

Hello Guys, I'm using the package RankProduct to determine the differential expression of genes in 2 classes. The importance of the thing is to know: - How can I determine which class is the class of up-regulated genes and which to the down regulated gene - How can i interpret the results : $pfp, $RPs, $RPrank, Orirank,

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)

Dear R-users! I am using R1.2.0 under Windows NT4.0, and have data of the following form: > #simple example of data structure: > x <- data.frame(group=LETTERS[1:3], class1=1:3, class2=4:6) > x group class1 class2 1 A 1 4 2 B 2 5 3 C 3 6 I would like to convert this to a data.frame y of the following form: > y group class counts 1

Hi, I'm working with Version 1.9.0 (2004-04-12) on Windows 98/NT/2000 where I found the following wrong (?) behavior of setValidity(). I already mentioned this on the R-help list (2004-06-11, was "setValidity changes Extends?") , but as I got no answer I tried to figure out what's happening. Well, setValidity() behaves not as I would expect (something about the

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

Hi, The unary forms of is() and extends() report that data.frame extends list, oldClass, and vector: > is(data.frame()) [1] "data.frame" "list" "oldClass" "vector" > extends("data.frame") [1] "data.frame" "list" "oldClass" "vector" However, the binary form of is()

Hi, Does this code should works ? elm.getElementsBySelector(''UL.class1 > LI.class2''); I have an error caused by "UL.class1 > LI.class2" - Does CSS Selector ">" works ? - What is the exact ? may be "UL.class1>LI.class2" Regards, -- Jean-Philippe Encausse - R&D Jalios SA Jp [at] encausse.net - http://www.encausse.com -

Hi, When starting an embedded R I encounter the following issue under certain conditions: ``` Error: package or namespace load failed for ?utils? in if (.identC(class1, class2) || .identC(class2, "ANY")) TRUE else {: missing value where TRUE/FALSE needed ``` (more such errors for grDevices, graphics, and stats) And in the end: ``` Warning messages: 1: package ?utils? in

Hi, I'm new 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

Yes, 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)'

Hello, I don't manage to see if you have already focussed on this point in some previous messages so I post my question: I have a little problem with the S4 style of programming. I tried to formalize my question: please consider the following example that you can run I think: #------------------ setClass("my.class1", representation( my.list =

I am using R-2.10.1 binary from CRAN on a WinXP Pro system. I also use SAS v9.2 on the same box. I just started using the SAS ODBC driver that comes with version 9 of SAS. I have been able to set up an ODBC source for SAS datasets using the driver, and then with RODBC I am able to read a sample SAS dataset. > library(RODBC) > ch <- odbcConnect('sasodbc', believeNRows=FALSE)

Hello, I have a question concerning "setClassUnion". I'm working with R 2.0.0 Patched (2004-10-06) on windows 2000. I tried to use "setClassUnion" in a package I am currently working on. The situation is similar to the following example: The DESCRIPTION file has entries: Depends: R (>= 2.0.0), methods Imports: methods LazyLoad: yes The NAMESPACE file has
