...all help for creating an instruction that calls e member method of an object. I suppose that this is not a headache but I am impatient in learning :) I would be very thankful if you can show me an example snippet code that does this in LLVM. Below is described my case. Let's say I have a class TestClass class TestClass { int testMethod(int a); } and I want to create a call instruction that calls obj.testMethod(input) where obj is an instance of TestClass TestClass obj; // I have this declared prior int input = 1; // I have declared prior int output; // I have this declared prior too output...

I don't understand the following behavior for a simple S3 class. The auto-printing at the command line doesn't behave as I expect. I'm probably missing something, but it might be a bug. > print.testClass <- function(x, ...) cat("Class:", class(x), ":", x, "\n") > structure(1, class = "testClass") Class: testClass : 1 > print(1 * structure(1, class = "testClass")) Class: testClass : 1 > 1 * structure(1, class = "testClass") #...

...r vectors. tm (version 0.5) saves corpora as lists with a class attribute of c("VCorpus", "Corpus", "list"). I don't actually need the class-specific attributes, I only care about the list itself. Here's a simplified example of my problem: > setClass("testclass", representation(slot="list")) [1] "testclass" > a = list(a="1", b="2") > class(a) = c("VCorpus", "Corpus", "list") # same as corpora in tm v0.5 > x = new("testclass", slot=a) Error in validObject(.Object)...

Hi, I'm trying to create a package that contains reference class definitions from which users can create reference objects, but there seems to be something awry. My toy example creates an empty package via package.skeleton('TestClass') to which I add the following R code: TestClass <- setRefClass('TestClass',fields=c('name')) Unfortunately my R console output bears this: > library(TestClass) > TestClass$new(name='foo') Error: attempt to apply non-function > getRefClass('TestClass...

...ence class generator? I have tried adding a "new" method to the methods of the class, but that is obviously not correct. I have also tried adding it to the class generator, but the class generator still uses the default constructor. As a simple example, this is the current interface: TestClass <- setRefClass ("TestClass", fields = list (text = "character"), methods = list ( print = function () {cat(text)}) ) test <- TestClass$new (text="Hello World") test$print() I would like to override $new(...) to be something li...

...ost some of the guidelines. Anyway this is my problem: Version: R version 2.15.2 (2012-10-26) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) I want to make an S4 class that use the output object of the function of nls.lm as a slot: setOldClass("nls.lm") setClass ( Class="TestClass", representation=representation( lmOutput = "nls.lm", anumeric = "numeric" ) ) Now, if I want to call this class in a "constructor function" I can do something like this (correct?): myConstructor <- function() { return(new("TestCla...

...ds,   I'm still studying S4 classes and I have a question about slot assignment. Why would I have to use a special setter method [example 2 below] if I can assign data to a slot directly when I call new() [example 1 below]?   ## first way to do it (the idiosyncratic way?) setClass(Class = "TestClass", representation = representation(myDf = "data.frame")) setGeneric(name = "doStuff", def = function(object, ...){standardGeneric("doStuff")}) setMethod(f = "doStuff",    signature = "TestClass",    definition = function(object, ...) {      retu...

Dear list, When playing around with the "[" method for S4 classes I noticed that it gets called twice in my example. setClass("testClass", representation(a="character")) setMethod("[", signature(x = "testClass", i = "ANY", j="ANY"), function (x, i, j, ..., drop){ print("void function") } ) > x <- new("testClass") >...

...e former copies the function to the object's environment (with some attributes attached), and the latter just return NULL (unless it has already been accessed once with .self$x). Is this how it's supposed to work? Here's an example that illustrates: https://gist.github.com/wch/7013262 TestClass <- setRefClass( 'TestClass', fields = list(a = 'ANY'), methods = list( initialize = function() { e <- environment() pe <- parent.env(e) ppe <- parent.env(pe) # The environment of this object print(ls(pe)) # The environment o...

Hi, the following Code demonstrates an possibly Error in R (or you can explain me, why this happens, thanks in advance) Code: ##################################### testClass <- function( stackData= c()) { list( write= function( ...) { sChain= "" for( s in c( stackData, ...)) { sChain= paste( sChain, '"', sub( '"', '\\\\"', s), '"', sep, sep='') } write( sChain, fHandle, a...

Dear list, can someone explain to me why deparse(substitute(x)) does not seem to work when x is of a user-defined S3 class? In my actual problem, my print method is part of a package, and the method is registered in the NAMESPACE, if that should make a difference. > print.testclass <- function(x,...){ xname <- deparse(substitute(x)) cat("Your object name is",xname,"\n") } testlist <- list() testlist[[1]] <- 1:10 class(testlist) <- "testclass" # This does not work as expected: > testlist Your object name is structure(list...

Hi, I have an problem that I can''t get resolved. I have an hash like www.krzywanski.net/archives/703.
