similar to: Running examples with R5 constructor from package failing

Hi, New to this list, and glad I found R5 which si a great improvement to R for my work. Something seems odd anyway, when I do a setRefClass, the initialize method execute at the class definition. I would like it to execute only when an instance is created. How can I do that? I found no way to test if the code execution is when the class definition happens or when a $new instance is created.

Hello, I wrote a class like so: > rcfdpsuperclass <- setRefClass( > Class="rcfdpsuperclass", > fields = list( > RcfpdVersion = "character"), > methods = list( > initialize = function(){ > 'Populates fields with defaults and lock as appropriate' > initFields( > RcfpdVersion =

Are there any plans for CRAN to support NEWS files in markdown? Bit of a hassle to go the the package?s Github (or other like) site to read NEWS.

Hi list, is there a way to define some kind of private Variable? I would like to prevent the user from manipulating fields on his own, in order to not destroy data structures. The problem is, that as soon as the variable exists in the environment it is accessible via t$secret_value. test <- setRefClass("test", fields=list( secret = function(value){ cat("the function was

It's disappointing that many packages do not have a NEWS file. Perhaps CRAN should require NEWS or CHANGELOG, as long as the system is being reformed to potentially accommodate markdown anyway. -Thomas Thomas J.

I realise this is not directly related to the topic but if changes are afoot would it be possible to make the use of any sort of news or changelog more prominent in the documentation? I maintain one of the CRAN task views and when someone updates his/her package it is much, much easier for me to see what has happened and if I need to update the text if they supply a news or changelog.

RStudio is just displaying HTML whenever it shows you anything in the Help pane. or being about to run something like show_news(?packagename?).

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",

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 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

> 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]]

As of rev. 61035 in r-devel, setRefClass() now returns a generator function, as setClass() has done since 2.15.0. The convenient style is now: mEdit <- setRefClass("mEdit",......) xx <- mEdit(data = xMat) instead of xx <- mEdit$new(data = xMat) The returned object still has fields and methods accessible as before. See the "Value" and "Reference Class

Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def
