similar to: Plans to improve reference classes?

Apart from speed, the most important advantage of R6 over ref classes is that's it easy to subclass a class defined in package A in package B. This is currently difficult with ref classes because of the way it does scoping. (And I think it's difficult to fix without fundamentally changing how ref classes work) Hadley On Mon, Jun 22, 2015 at 8:49 AM, Michael Lawrence <lawrence.michael

Could of requests: 1) Is there any example or writeup on the difficulties of extending reference classes across packages? Just so I can fully understand the issues. 2) In what sorts of situations does the performance of reference classes cause problems? Sure, it's an order of magnitude slower than constructing a simple environment, but those timings are in microseconds, so one would need a

While using parallelization R seems to clone all environments (that are normally passed by reference) that are returned from a child process. In particular, consider the following example: library(parallel) env1 <- new.env() envs2 <- lapply(1:4, function(x) env1) cl<-makeCluster(2, type="FORK") envs3 <- parLapply(cl, 1:4, function(x) env1) envs4 <- parLapply(cl, 1:4,

This is all normal, a fork cluster works with processes, that do not share memory. When you create a fork cluster, you create a new process, that has the same memory layout as the parent. But from this moment its memory is independent of the parent process. When parLapply is done, the results are serialized and copied back to the parent process. The serialized environment is independent of the

Dear community, I am having a class, let's say Person, Person <- R6Class("Person", public = list( idPerson = NULL, name = NULL, age = NULL, initialize = function(idPerson = NA, name = NA, age = NA) { self$idPerson <- idPerson

I'm writing some code that does a bit of introspection of R6 classes and am wondering about the "classname" parameter. Its the first parameter to the "R6Class" class generator generator function, and the few examples I've looked at on CRAN set it the same as the name of the generator function, for example, from the docs: Queue <- R6Class("Queue", .....)

Has anyone posted an RPM (for i386) for Dr. Chong Gu's new gss package? I am trying to install it on a Linux system too small to compile the Fortran code directly. Thanks for any help.

Hello, I am trying to get my synology DS 418play to connect to my new INTERNET600U UPS, but it appears not to work. I contacted TrippLite and they said the unit is using a new comm protocol 3024. Is there a way to make this work with usbhid-ups? More details of my story here: https://community.synology.com/enu/forum/1/post/132984 Thanks for your help! -Troy

Dear R-users, I am working to install Chong Gu's new gss library on my Linux system (Redhat 5.1/i386), and have run into the following roadblock: Dr. Gu's R code is a front end for a package of Fortran routines called RKPACK. While I have no trouble compiling the individual bits of Fortran code with fort77 in Linux, I don't know how to link the resulting *.o files into a shared

Dear community, I want to use conformal prediction to measure how good are my svm-regression predictions (having used library e1071). I have gone through the conformal package documentation. But I'm pretty newer and need some more and detailed examples. Can anybody help me? Thanks in advance, [[alternative HTML version deleted]]

Hi all, I got a silly bug when compiling our project with the latest Clang. Here's the outputted assembly: > tst r3, #255 > strbeq r6, [r7] > ldreq r6, [r4, r6, lsl #2] > strne r6, [r7, #4] > ldr r6, [r4, r6, lsl #2] > bx r6 For the code to execute correctly, either the _ldr_ should be a _ldrne_ instruction or the _ldreq_ instruction should be removed. The error seems to

So I tried to do this: %r8 = load <2 x double>* %r6, align 16, !"nontemporal" and the assembler doesn't like it.

fixes compilation issues with recent envytools, because movw was removed from fuc5, because it doesn't exist there anymore. The current code is most likely broken for fuc5 hardware as well and might have triggered all kinds of random memory reclocking fails. Changes in fuc3 binaries are tue do opcode optimizations using shorter opcodes when possible. Signed-off-by: Karol Herbst <kherbst

Sound reasonable? Well, that's a rat's nest. I backed up and thought maybe I have the metadata syntax wrong. So

Hi, I've been working on a Blackfin backend (llvm-3.6.0) based on the previous one that was removed in llvm-3.1. llc generates codes like this: 29 p1 = r2; 30 r5 = [p1]; 31 p1 = r2; 32 r6 = [p1 + 4]; 33 r5 = r6 + r5; 34 r6 = [p0 + -4]; 35 r5 *= r6; 36 p1 = r2; 37 r6 = [p1 + 8]; 38 p1 = r2; p1 and r2 are in different register classes. A p*

If I'm understanding what's going on in this test correctly, what's happening is: * ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize * In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6) * The function has three arguments, so those three plus the register we need to hold the
