similar to: Dots argument in apply method

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

Hi, I'm developing in S4 and I wanted to see the methods for a specific class using showMethods but I didn't succed. Can someone help ? See the example below. setClass("myclass", representation( name ="character" ) ) setGeneric("mymeth", function(obj, ...){ standardGeneric("mymeth") } ) setMethod("mymeth",

Hi, I have a nicely printed table of results generated by R's > print(myresult) where myresult is a "data frame". I am trying to put this table into a powerpoint slide for presentation without re-typing and re-formating, i.e., present it as it is in the R window. This saves time when there are a lot of tables to be presented. I tried > sink("myresult.txt") >

Howdy, I'm setting up several gluster 3.12 clusters running on CentOS 7 and have having issues with glusterd.log and glustershd.log both being filled with errors relating to null client errors and client-callback functions. They seem to be related to high CPU usage across the nodes although I don't have a way of confirming that (suggestions welcomed!). in

Hi Ezra, Thanks for the great work on BackgrounDRb. I have come across a couple of problems. 1. I wanted to define a simple class in the worker file to wrap up and pass back some data to my controller. It seems that if I create the class either inside or outside of my worker class (in the same file) it gets wrapper by a DRb::DRbUknown object and therefore cannot be accessed from my controller.

Hi all; Is it possible to modify the "@" operator that it can handle references (or external pointers) of S4 Object instead of the real Objects? Or is there any technical or compatibility issue which make it impossible? I look forward to hear from you and also hope that you don't hate me for my nooby question. Yours sincerely, Rudolf Biczok [[alternative

Sam, You might want to give glusterfs-3.12.1 a try instead.

Hey everyone, I know that I can call 'R' from other scripts, and that I can make command calls from 'R' (e.g., using system() ). But how can I get 'R' to RETURN values to the script that called it. E.g., I would like to be able to do something like the following (as a simpler example) from a bash script: #!/bin/bash myTest=echo /usr/local/bin/R --no-restore

Thanks Milind, Yes I?m hanging out for CentOS?s Storage / Gluster SIG to release the packages for 3.12.1, I can see the packages were built a week ago but they?re still not on the repo :( -- Sam > On 18 Sep 2017, at 9:57 pm, Milind Changire <mchangir at redhat.com> wrote: > > Sam, > You might want to give glusterfs-3.12.1 a try instead. > > > >> On Fri, Sep

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), ...) {

Dears, I have a question about copying reference objects using the initialize method. 1) If the latter has no arguments, there is no problem to copy an object. myClass = setRefClass("myClass", fields = list(value = "numeric") ) myClass$methods(initialize = function(...){ ? value <<- 1 ? callSuper(...) }) newObject = myClass$new() newObject$value = 2 copyObject =

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 =

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

FYI - I've been testing the Gluster 3.12.1 packages with the help of the SIG maintainer and I can confirm that the logs are no longer being filled with NFS or null client errors after the upgrade. -- Sam McLeod @s_mcleod https://smcleod.net > On 18 Sep 2017, at 10:14 pm, Sam McLeod <mailinglists at smcleod.net> wrote: > > Thanks Milind, > > Yes I?m hanging out for

Hi all ! I noticed a strange behaviour of the function `class<-` when a class-specific '[[.' method is defined. Here below a reproducible example : #-------------------------------------------------------------------. counttt <- 0 `[[.MYCLASS` = function(x, ...) { counttt <<- counttt + 1 # browser() x = NextMethod() return(x) } df <- as.data.frame(matrix(1:20,

Dear list: I am looking for a good way to create an S4 class that would extend numeric, but would allow NULL instead of data as well. As far as I can see there is no way at the moment to do that, but please correct me if I am wrong. The best solution I came up with so far was the following (it also indicates a problem of using setClassUnion with numeric as one of the classes): I define a class

Dear all, I have created a new S4 class with name "MyClass". Please see below for it's definition. Now I want to create a method for the show() function for this class. In defining this method, what I want is, once user would like see an object of this class some values will be displayed. Then R will ask for **press Enter**. Once user presses enter then, remaining values will be

Dear All, In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example: myfun <- function(y) { out <- list(y=y) class(out) <- "myclass" return(out) } print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5)) myfun(1:4) # prints: [1]

Hi R-helper! I have problem with setMethods for "[". Here is example : setClass("myClass", representation(ID.r = "numeric", ID.c = "character", DAT = "matrix")) to.myClass <- function(ID.r, ID.c, DAT) {     out <- new("myClass", ID.r = ID.r, ID.c = ID.c, DAT = DAT)     return(out)       }       setMethod("[",

Hi R-Help, Please consider the following simple case: I have a class like setClass("myClass", representation(x="matrix", y="character")) and I would like to use the method *"["* for a *myClass* objects (but changing the default *drop* argument from TRUE to FALSE): setMethod("[","myClass", function(x,i,j,...,drop=FALSE)
