similar to: R5 multiple inheritance

Hi all - I've been working on a lite ORM and database abstraction package for R. Formatting complex queries by hand has always been an error-prone hassle, so I've tried to do away with that as much as possible, instead, using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this

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 =

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

In ARM.td, I see that the ProcessorModel for cortex-r4, cortex-r4f, and cortex-r5 (as well as r7 and r8) is based on "CortexA8Model", which seems incorrect. When this was added in 2015, there were also comments associated with this configuration, such as "// FIXME: R5 has currently the same ProcessorModel as A8" (later removed). The processor model for Cortex-r52 appears to

I have installed Lotus Notes r5 on a Debian box via wine, and I did this by "wine /path to setup.exe" and now when I execute "wine /pathtonotes.exe or /pathtonlnotes.exe" a splash screen for notes r5 comes up and goes away and wine reports it as below: Wine exited with a successful status Debian kernel 2.4.25 wine version 0.0.20040309-1 notes version 5.0.10 Jim

I am having an issue with reference classes (R5) in a package I am developing. They have both been illustrated in the `roxygentest` package I've got hosted on Github [1].? When I run `R CMD check .` on the source directory of my package I am told that: > Error: could not find function "Blob" However, when I install and load the package, I can successfully run the command in the

Changes were committed today to the r-devel version of R to make S4 and S3 classes (and abnormal object types such as "environment") work together more consistently. Basically, S4 classes can now contain any S3 class or object type, and should now inherit S3 methods for these. Also, the main practical problem with defining S3 methods for other S4 classes (namely, that S4

Dear list, In a function, I don't care if my input has class 'integer' or 'numeric', so I wanted to use 'inherits()' to control for that. However, this function tells me that an actual object of class 'integer' does not inherit from class 'numeric'. The class def of 'integer' does state 'numeric' as one of the superclasses. Isn't

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.

i have a problem with wine, version 20020411 and lotus notes r5. i'm starting wine notes.exe and the install routine is going on. after input user - id and authentification on id, the wine session halted by "please give me your timezone". but i can't select a timezone :-)) i can't leave this window, i must skip on terminal the wine session with ctrl+c. is this a well-known

Hello guys, native drivers are mad for my laptop: Downgrade to native centos kernel vmlinuz-3.10.0-327.18.2.el7.x86_64. fglrx glxgears around ~800 in 5 seconds my test with amdgpu kernel 4.6 (intel vs amdgpu): [andy at localhost ~]$ cat /proc/version Linux version 4.6.0-1.el7.centos.x86_64 (andy at localhost.localdomain) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC) ) #1 SMP Thu May 19

A recently committed revison of R-devel (47740) has introduced a new mechanism for ordering superclasses consistently, with related changes for selecting inherited methods. As part of the process, a function testInheritedMethods has been introduced that examines method selection for the relevant subclasses and reports ambiguities. Maintainers of packages that have methods involving multiple

I''m getting some weirdness trying to use a select widget to choose the type from a collection of three objects sharing a database table via single-table inheritance (STI). I''d be grateful for any advice on whether it''s a bug or a feature, if a feature why and how I can more easily do what I''m trying to do. So I have the usual STI setup, with a

Hello there, would you please look into my codes? Here I have following: > set.seed(100) > samp <- sample(c(1,-1,0), 20, replace=T); samp [1] 1 1 -1 1 -1 -1 0 -1 -1 1 -1 0 1 -1 0 0 1 -1 -1 0 Here I want to calculate the length of each unique number for above vector. How can I do that? Thanks in advance [[alternative HTML version deleted]]

A very simple question. With a data frame like this: > n = c(2, 3, 5) > s = c("aa", "bb", "cc") > df = data.frame(n, s) I want df$s[1] or df[1,2], but how can I get rid of the extra line in the output about the factor levels: > df$s[1] [1] aa Levels: aa bb cc Thanks, Gang

Hi, I'm investigating converting some S4 classes to reference classes and have a question about inheritance. The primary data structure for the original S4 class is a 3-d array. Using the "contains" parameter when defining the class permits me to inherit all of the array-related methods. Of particular utility for me is the ability to access the array via [] indexing. It all works

Dear Developers, In current implementation of validity method, objects are first coerced to superclass (slots are striped). Thus, it is not possible to write validity method which would perform some checks on children slots. Say, I want to check if number of slots in a class is equal to "n": setClass("A", representation(a="numeric", n="integer"),

can anyone tell me how before filter can call the private method audit which from the parent class ? because the bank controller has a private method called audit, this one should not be inheritance by VaultController, so how the before_filter use the private method audit ? if the child class can use the parent class private method . does it break encapsulation ? does the private has any sense

Fellow R programmers, I'd like to submit SQLDF statements with R objects as column names. For example, I want to assign "X" to "var1" (var1<-"X") and then refer to "var1" in the SQLDF statement. SQLDF needs to understand that when I reference "var1", it should look for "X" in the dataframe. This is necessary because my SQLDF

I have a small idea as to what's going on now; at least, why exporting the class resolves this particular issue. Firstly, when an S4 class is not exported, the associated '.__C__<class>' object is not made part of the package environment. For example, I see: > getAnywhere(".__C__SubMatrix") A single object matching '.__C__SubMatrix' was found It
