similar to: Question about copying reference objects using the initialize method

Dear list, I'm wondering if the following error I'm getting is a small bug in the Reference Class paradigm or if it makes perfect sense. When you write an explicit initialize method for a Ref Class, can you then make use of '.self' WITHIN this initialize method just as you would once an object of the class has actually been initialized? Because it seems to me that you can not.

I need some help in defining a "print" method for my new S4 class definition. So fer I have worked like this: setClass("MyClass", sealed=F, representation(slot1 = "list", #create a new class slot2 = "vector", slot3 = "vector", slot4 = "vector")) setMethod("print",

> setRefClass("Foo", fields = list()) Error in setRefClass("Foo", fields = list()) : A list argument for fields must have nonempty names for all the fields In my opinion, the above should not fail. There are no fields. Thanks, Michael [[alternative HTML version deleted]]

Hello, I am trying to recursively append some data from multiple files into a common object For this, I am using in a loop NewObject <- rbind(NewObject,tempObject) For the first loop, obviously there is no NewObject ... so I wanted to do NewObject <- tempObject[0,] Now when it loops again I want to put the statement do "NewObject <- tempObject[0,]" inside a if statement

Dear list, I wonder how to write methods for the function 'as' in the sense that I can call 'as(object, Class, strict=TRUE, ext)' and let method dispatch figure out the correct method. AFAIU, there is a difference between, e.g. 'as.data.frame' and the methods of 'as()' as stated above since the former depends on arg 'x' instead of 'object',

Dear list, is it possible that method dispatch checks for superclasses/virtual classes before checking "ANY"? I'd like to build a generic initialization method for all my Reference Class (say "MyDataFrame") objects by having them inherit from class, say "MyRefClassVirtual" (which would have to be a virtual S4 class; there are no virtual Reference Classes,

I was cursing Matlab again today (what else is new) because the default action for every Matlab command is to spew the result to the console, and one must remember to put that darn ";" at the end of every line. So I just wondered: was there ever a discussion as to providing some modified version of the "<-" and "->" operators in R to do the reverse?

Greetings, I am trying to use Reference Class methods in Snowfall, using R 2.12.1 on Ubuntu Natty. Using then directly seems to work (stanza 2 below), but using them indirectly does not (stanza 3 below). I get an "attempt to apply non-function" error. In addition to exporting the instance of the object I created to the Snowfall slaves, I also made several attempts to export the

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and

Dear John and others, I've been wondering about whether there's any way to indicate a "nil" reference class object, which will represent "no value", and be tested for, but not fail the internal type checking. NULL is the obvious choice (or seems so to me), but can only be used if an explicit class union is created: > Foo <- setRefClass("Foo") > Bar

Hi again List, Well this time I’m writing for a friend (really J). He needs to create a distance matrix based on an abundance matrix using the 1-Pearson’s R index. Well I told him to look at the proxy package, but there is only Pearson Index. He needs it to perform a clustering. Well, as soon as he told me there proxy only had the Pearson index I thought: “He could just do something like

Hi everyone, I have trouble to use RWeka, I tried: (w=weather dataset, all preditors are nominal) > m<-J48(play~., data=w) > e<-evaluate_Weka_classifier(m,cost = matrix(c(0,2,1,0), + ncol = 2),numFolds = 10, complexity = TRUE,seed = 123, + class = TRUE) it gives me exactly what I want, but when I tried the same classifier on the other published data: (iris dataset has all numeric

Dear R users, Would it be difficult to change the code of stepAIC (from the MASS library) to use AICc instead of AIC? It would be great to know of someone has tried this already. Best wishes Christoph.

Hello all, I am attempting to run an R script that makes use of RWeka. I am running SuSE Linux 9.3 with Java 1.5.0_06, R version 2.2.1, Weka 3-4-7, and Rweka 0.2-1. CLASSPATH="/usr/local/weka-3-4-7/weka.jar:/usr/local/JGR/JGR.jar" I receive the error: NewObject("weka/core/Instances","(Ljava/io/Reader;)V",...) failed Exception in thread "main"

Hi guys, i''ve just installed xen 4.0. Since always blktapctl has never worked on my dell 1950III. I even posted a bug but so far i can''t use tap:aio or similar. I thought that with version 4 this would work, but it didn''t. I still see syslog errors from blktap version 1.0.0. Today i wanted to try version 2 I found on the xen/tools source folder. I compiled the source

This bug appears intermittently in R CMD check when reference classes have finalize methods. The problem is that garbage collection can be run after the methods package is no longer available. It affects (periodically) the Bioconductor AnnotationDbi package as well as packages that contain Rcpp classes. To reproduce: library(methods) a = setRefClass("A",
