I have found some "issues" (bugs?) with nls confidence intervals ... some with the relatively new "port" algorithm, others more general (but possibly in the "well, don't do that" category). I have corresponded some with Prof. Ripley about them, but I thought I would just report how far I've gotten in case anyone else has thoughts. (I'm finding the code

Tengo que preparar un Dataset que termine siendo un resumen de cuenta contable a partir de los datos del diario contable de una empresa que el script va filtrando cuenta por cuenta. He podido importar los datos con variables: fecha , concepto, valor debe, valor haber y me falta una variable que sea el saldo. Sucede que el saldo se tiene que calcular fila a fila, es decir sumando el valor debe y

Function arguments are not pass-by-reference... they are pass-by-value. You need to return the altered object to the caller when you are done messing with it. Note that R is a data processing language... your example will not scale to real world use cases because you make no use of vectorization to handle multiple accounts. It is better to focus on the functional aspect of computing and let the

I searched the web and the list archives for a solution to this, but didn't see anything, so here goes. I'm new to tcltk. I'm trying to change the contents of a tkentry widget when a button is pressed. Once I get that working, the widget will be read only to the user. Here is some toy code: ############### require(tcltk) thisEnv=environment() tt<-tktoplevel() Name <-

In the below code fragment, print(arg) always prints the last element of rekeningen$rekening. Is this because of lazy evaluation? I.e. arg is evaluated at the time the button is pressed? And, if so, how can I avoid this? I tried function() {force(arg); print(arg)} but that didn't work either. Thanks, Jeebee. for(rek in seq(1,nrow(rekeningen))) { arg <- rekeningen$rekening[rek]

Hey Xiaoming, Thanks for those source codes. Can you please explain what this llvm-memory-profiling.patch does ?

Hey John, Thank you for the detailed reply. I tried to figure out myself which IR should I use for my purpose ( Clang's Abstract Syntax Tree (AST) or LLVM's SSA Intermediate Representation (IR). ), but couldn't really figure out which one to use. Here is what I m trying to do. Given any C/C++ program (like the one given below), I am trying to insert calls to some function, before and

The patch file is a diff file generated by "svn diff". It is about other modifications such as adding some lines to make files to make the added .c and .cpp files compiled. You may apply the patch file to LLVM source code by using a "patch" command or make the changes manually by reading the patch file. Xiaoming On Wed, Sep 28, 2011 at 6:05 AM, Himanshu Shekhar

Hey guys, I have seen your interesting conversion. I am new for LLVM as well as clang compiler. I am going to use it now. it is quite difficult when someone starts it from scratch. But it is enjoyable and it is possible to familiarize with the environment by short time. Am gonna to use clang + llvm to generate AST from source code by using clang and to do high level transformation. Then I want to

Hi, Himanshu. I once wrote an LLVM IR-based memory profiling pass. Basically, I followed the code for EdgeProfiling. The source code is enclosed here, which worked with LLVM 2.8. Hope it is helpful. MemoryProfiling.cpp---the instrumentation pass, which inserts profiling function calls into the original program MemoryProfiling.c---the profiling library containing the profiling calls

Hello, What you're describing is basically the parsing and codegen portions of clang. I'd suggest reading through the code there and posting to clang-dev if you have any specific questions. The clang devs are more likely to see your questions there as not all of them also hang out here. Regards, Jim On Sep 28, 2011, at 8:28 PM, eyasu getahun <eya.get at gmail.com> wrote: >

I just read that LLVM project could be used to do static analysis on C/C++ codes using the analyzer Clang which the front end of LLVM. I wanted to know if it is possible to extract all the accesses to memory(variables, local as well as global) in the source code using LLVM. Is there any inbuilt library present in LLVM which I could use to extract this information. If not please suggest me how to

An application that run without flaw last week has been reported to crash with an error that says that a conversion from char to datetime has given a date outside range. This very application runs OK today in production (fortunately :-), and the difference in both SQL Servers is just that the one where the exception has started to appear has Spanish conventions. I can''t give

Dear R users, I have two related questions about scoping and data encapsulation. One is fairly specific - I am looking at "scoping.R" which is used in demo(scoping) - it's an example of lexical scoping and encapsulation. Where is the 'total' stored? It is not an attribute in 'ross' or 'robert' however, functions like balance() have access to it. Is it more

Hi all - I know this must be really easy to do, but I can''t for the life of me figure it out. I have about 100,000 rows I need to migrate over into rails using a migration. Right now, I select all of them out of the old database and do a series of: ... new.col = old.col ... new.save ... Problem is each one is it''s own transaction. And it''s slow. I''d
