similar to: mtrace and debug

Dear useRs, I am experiencing very strange error with Mark Bravington's package "debug". I haven't seen them before. Here is the sample session > library(debug) Loading required package: mvbutils MVBUTILS: no "tasks" vector found in ROOT Loading required package: tcltk Loading Tcl/Tk interface ... done > x<-function() return(1) > mtrace(x) > x() Error

I find the R debug package very useful. I've installed and used it on several of the machines I use, without problems, but on one machine I get the following error: Loading required package: mvbutils Loading required package: utils MVBUTILS: no "tasks" vector found in ROOT Loading required package: tcltk Loading Tcl/Tk interface ... done [Previously saved

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()

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

Dear All, I encountered the following problem: fun1 <- function(x){ 2*cos(x) } >library(debug) > mtrace(fun1) > fun1(0.1) Error in all.levs[[j]] : subscript out of bounds > sessionInfo() R version 2.5.0 (2007-04-23) i386-pc-mingw32 locale: LC_COLLATE=Polish_Poland.1250;LC_CTYPE=Polish_Poland.1250; LC_MONETARY=Polish_Poland.1250;LC_NUMERIC=C;LC_TIME=Polish_Poland.1250 attached

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 memory leaks. $ mtrace <myprogram> $MALLOC_TRACE But In

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

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 deleted]]

I don't know the right computer science words for this question, I'm afraid. Apology in advance. How do you find your way around in somebody else's code? If the user runs a specific command, and wants to know how the data is managed until the result is returned, what to do ? I've tried this manually with tools like mtrace and browser. This is a bit frustrating because the

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

Hello I am trying to follow the instruction in README.debug on how to debug a code I wrote, so since it only shows the steps on how to debug a built in function and not a code in an *.R file, so ok, let me do this and maybe later I can find out how to code my code in filename.R. now > library(debug) Loading required package: mvbutils MVBUTILS: no "tasks" vector found in ROOT Loading

Hello, first, big thank you to the developers of R, the release of recent version is very nice.! Well, it seems that I've messed up my current installation by using two update mechanism at the same time on my Debian Sid box. That is : 1)Debian Way per apt-get freshing up my R installation 2) irregularily "update packages()" from within R. I guess this obviousely resulted in

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 an error. -- View this

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")} > mtrace(foo) > foo() # A tcl/tk windows open

Hello, hopefully someone will remember my previous problem to load the Rcmdr library from within GNU R resulting in an error message: "libnvidia-tls.so.1: cannot handle TLS data". Some suggestions have been raised by Christian Schulz and others that unfortunately didn't work around this error. Nevertheless I felt very grateful for your suggestions! This morning I investigated

Hi All: A couple of weeks back, I asked a question on the list that I was invited to provide an introductory lecture on R to a group of academicians in Kolkata. I thank all of you who had generously guided me in providing me web links and words to the wise. Time to give back. I did the presentation on introduction to R and uploaded the presentation files at the following site:

Deal R , when I use the package debug, mark a function with mtrace() and enter into the browser like mechanism of debug a window displaying the code of the marked function with the current line highlighted usually appears. When I use GUIs other than ess or the standard R console sometimes this window is totally transparent so it is not possible to see any code in it. After closing/resizing
