Hi, everyone. I am using a fair amount of closures in my code. Problem i am experiencing is i cannot figure out how to mtrace functions defined within a function. There must be some way to name such function for mtrace to see it and let me step into it. For example, say i have code mymodel<-function(){ data<-numeric(0) build<-function(){ data<<-1 } m<-list() m$build<-build m } How do I...

Hi all, I am using "mtrace" malloc debugging utility to trace memory leaks in my application. I followed following steps: 1. Added mtrace() function in the beginning of my main function. 2. exported the MALLOC_TRACE environment variable. $ export MALLOC_TRACE=memory.log 3. Run the program 4. trace the program for...

If it's your own code, my recommendation would be to predefine the function and then mtrace it, as you suggest. But I can see that this isn't always easy, e.g. if you're trying to debug a system function. Because every little operation in R is actually a function call, it's probably not very useful for 'mtrace' to have a step-into mode. [Anyway, whether useful or not,...

...cember 2003 there is a package mvbutils mentioned. So I started to install this package from within R > install.package(mvbutils) I receive an error essage that this package is not found! Is due to a merge,removal or rename of this package? When I try to follow this article by typing i.e: mtrace I receive also an error message, that function mtrace is not found? Where do I find the above mentioned package? thanks Thomas ---------------------------------------------------------------------------------------- platform i386-pc-linux-gnu arch i386 os linux-gnu system i386, li...

I use windows xp. When trying to use the function mtrace from package debug the window that should open with the function to be debugged do not show any text at all. It shows only a part of my desktop. Does anyone know why. Is there any imcompatibility between windows xp and debug package. Thanks in advance. Enio Jelihovschi [[alternative HTML version...

Hi all, Since three month ago I started working with R professionally, I never did it before, so I am such a newbie. I am having some problems using the 'debug' package. I love this package, but most of the times I wanna use it it just fails :P When typing at prompt 'mtrace(myfunct)' most of the times I get the following error: "Error in x[[i]] : subscript out of bounds" I can't understand whats happening and I couldn't find any help surfing the net. I have the feeling it might be because of my coding style or something similar. Any help will b...

How do you debug methods of a reference class? I've been using mtrace, which is excellent, but i cannot figure out how to mtrace a reference class method. Maybe there is some other way to debug these, for example with ordinary trace? for now i am only able to use options(error=recover), which is not giving me idea where exactly in the code i am once i am stopped on a...

I am using getYahooData from TTR to get daily data. When i do it standalone, it is fine. It also works fine inside my code. However, when i run code inside mtrace(), i always get the following error: Error in xts(cbind(adj[[1]], adj[[2]]), index(obj)): order.by requires an appropriate time-based object After a lot of hand wringing, it looks to me that it happens because index in xts masks index in package mvbutils. Is there any way to avoid this type of...

Hello, In the past I have used intensively the mtrace function from the debug package, but now with my actual version of R(2.8.1) , it is impossible to use it anymore. I've updated all my packages, and I don't understand how solve this problem... Here is an example code : > foo<-function(){cat("Test Function")} > mtr...

Hello I need some help in figuring Bravington’s debugger out. Ok I have 2 functions, fun1 and fun2 saved in a ASCII file say filename is funs. Fun1 has a loop which calls fun2, fun2 has a loop which fails and I need to find out the value of the variables of the fun2 and fun1 loops at the specific iteration that fails. Both fun1 and fun2 loops will iterate thousands of times so line by line debug

I would like to be able to trace execution into calls below the current function, or to follow execution as calls return. This is roughly the distinction between "step" and "next" in many debuggers. I would also like to be able to switch to a location further up the call stack than the location at which I enter the debugger, to see the context of the current operations. Are

...nctions stopped working at about R1.6 with the arrival of 'namespace:base', and I'm anxious to find out what will happen when 1.7 arrives. But the question might be of more general relevance (hence my desire to get it in before "lockdown" on 9th April). I have a function 'mtrace' which is supposed to overwrite the "most findable" instance of its argument. 'mtrace' could be called either from the command line, or from inside another function (i.e. somewhere in a stack of temporary frames). Conceptually, what 'mtrace' does is: mtrace( fname) {...
