similar to: Seeking help to define method for show() for an S4 object

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",

Dear all, I am having problem to create a package when this package is supposed to have some newly created s4 class. Here is my workout: > #rm(list = ls()) > setClass("aClass", sealed=T, representation(slot1 = "vector", slot2 = "character")) [1] "aClass" > fn1 <- function(x, y, z) { + x <- x[1] + y <- y[1] + z <- as.character(z[1]) +

Hi, The man page for new() suggests that if 'a' is an object with slots "slot1" and "slot2" and C is a class that extends the class of 'a', then the 2 following calls should be equivalent: new("C", a, ...) new("C", slot1=a at slot1, slot2=a at slot2, ...) This is generally the case but I just ran into a situation where it's not.

Sorry in advance if this is too simple a question, but I'm stuck with some odd behavior and I can't find the text to rid myself of this (admittedly somewhat trivial) problem. Note that I've done generic programming with S3 "objects" in the past, but I've never really dabbled in creating S4 objects until now. So, I've created a new S4 class, call it

I get this error no matter what I do. I've tried switching to different locations on the TDM400p to no avail. I've got the card setup with the green module in slot1 and red in slot2. My config files are exactly like the "Configure Dev-Kit PCI (TDM11B)" example. http://www.digium.com/index.php?menu=configuration#TDM11B When I run ztcfg -v, I get: 2 channels configured.

Hi, I realize this is an old thread, but just wondering whether a conclusion was ever reached on this issue? I'm using formula(NULL) but it would be nice if default initialization worked for formula classes as well. Cheers, Josh On Thu, May 14, 2015 at 8:13 AM, Herv?

I'm curious how does hexagon hardware decide which slot to use for a given instruction? Is there special hardware to make that decision? I'm asking because I didn't see any information about which slot to use for a given packet. Is it even possible to pass this kind of information through assembly? Say hardware sees a packet and the packet tells it which slot to use. I would greatly

I have got another question on defining a method for print() function for my s4 class. Here is my class definition as well as what I have done till now: > setClass("Me", representation(x1 = "numeric", x2 = "numeric", y1 = "character")) [1] "Me" > setMethod("print", "Me", definition=function(x) { + cat("Values

Question: Does ext2/3 (or any other filesystem you know of) support a system call turning blocks within a file back into "sparse zeros", i.e. giving the blocks back to the filesystem? Background: I am working on a slotted fileformat where internal fragmentation occurs. One such occurrence is growth of the data in a given slot, which currently requires me to handle the

Dear all, Assume that I have an S4 class "MyClass" with a slot "myname", which is initialized to: myname="" in method("initialize"): myclass <- new("MyClass", myname="") Assume that class "MyClass" has a method "mymethod": "mymethod.MyClass" <- function(object, myname=character(0), ...) {

Dear all, I am trying to define "+" method for my newly defined s4 class which is as follows: setClass("Me", sealed=F,representation(x1 = "numeric", x2 = "character")) new1 <- new("Me", x1=2, x2="comment1") new2 <- new("Me", x1=3, x2="comment1") setMethod("+", "Me",

Dear all, Since my package is based on S4 classes, I would like to know how to add a slot to an existing S4 class without breaking the code of users of my package. Assume the following S4 class: setClass("MyClass", representation(name = "character", type = "character", data = "data.frame" ), prototype(name =

For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

Hi all, I'm trying to implement the matrix multiplication operator, which is S4 generic, for an old-style S3 class. The following works as expected: x <- 1:10 class(x) <- "myClass" setOldClass("myClass") setGeneric("myMethod", function(x, y) standardGeneric("myMethod")) setMethod("myMethod", c("myClass", "myClass"),

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the
