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

Hello, pointed to the article "Debugging Without (Too Many) Tears" of Mark Bravington in Rnews Vol 3/3, December 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

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

Dear all, I'm totally new to R. Recently I've been trying to use getYahooData in TTR package in order to download stock index daily open/high/low/close.

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()

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

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 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

Hi Jannis [I'm the author of package debug... I know this is 6 months after your query, sorry-- but I don't subscribe to R-help, and you didn't post to the maintainer!

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

library(xts) library(TTR) ndx = getYahooData("^NDX") aa = ndx$Close bb = aggregate(aa, as.yearweek, tail, 1) The last operation takes forever, and then the bb dates are messed up. The following produces the desired result: time(aa) = as.Date(time(aa)) bb = aggregate(aa, as.yearweek, tail, 1) The index of ndx and aa is of POSIXct (as reported by is(time(ndx))) , which apparently

Hello, all... I've been playing with the TTR package and quantmod, and I'm loading the Chicago Board of Exchange put/call ratio data via a simple read.csv call...

Hi, I'm trying to fit a hidden Markov model (mixture of Gaussians) to stock prices (Open, High, Low, Close) data. Here's my code: #First download the data with package TTR library(TTR) n <- 200 data <- getYahooData("GOOG", strftime(as.POSIXlt(Sys.time() - n*24*3600),format="%Y%m%d")) keep <-

A number of users have spotted a terminal problem with the 'debug' package under R2.4.0, along the lines of > mtrace(x) > x() Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' This arose from a bug in 'rbind.data.frame' in R2.4.0 itself. The bug is fixed in R2.4.0 patched, so 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
