similar to: Automatic traceback

Hi, I wonder how to have R automatically print stack trace produced by traceback upon errors during interactive uses. I tried the suggestions on http://old.nabble.com/Automatically-execute-traceback-when-execution-of-script-causes-error--td22368483.html#a22368775 and used options(error = recover) options(showErrorCalls = T) It just produces an extra message like "recover called

Hi I am using R scripts which are running remotely. To make debugging easier, I would like to have the possibility to execute traceback() automatically when an error occurs. Is this possible?

I would like to be able to do something like this: <<echo=F,fig=T,width=mywidth>>= ... @ with mywidth set in a previous code chunk. Is there a way to do this in Sweave? (Sorry for two questions in a row, I have been saving these up.) -- Michael

I am using R 2.4.0 and lattice to produce some xyplots conditioned on a factor and a shingle. The shingle merely chops up the data along the x-axis, so it is easy to identify which part of the shingle a panel is in by looking at the x-axis markings. I only want to have a strip at the top for the factor. Is this possible? I looked into calculateGridLayout() and it seems to me that there

Consider this plot: xyplot(mpg ~ disp | cyl, mtcars, strip=F, strip.left=T, layout=c(1, 3), scales=list(relation="free"), par.settings=list(strip.background=list(col="transparent"))) I want to have the "cyl" strip labels on the left side of the axis. Is this possible? Failing that, is it possible to remove the left axis and display it on the right

Hello, 1. The Situation : ------------------------ The stack traceback is not available when error ouccured in a try(....) -- test.R -------------------------------- f<-function(a){ return ( log(a) ) } try(f("A")) traceback() ------------------------------------------- I get the following message : > try(f("A")) Error in log(x) : Non-numeric argument to mathematical

Dear R experts---I may have asked this in the past, but I don't think I figured out how to do this. I would like to execute traceback() automatically if my R program dies---every R programI ever invoke. I guessed that I could have wrapped my entire R code into tryCatch( ... oodles of R code , error = function(e) traceback(), finally = cat("done") } but the traceback docs tell

Has something changed with traceback's in R-patched? When I running the examples for ?traceback, I get > foo <- function(x) { print(1); bar(2) } > bar <- function(x) { x + a.variable.which.does.not.exist } > foo(2) # gives a strange error [1] 1 Error in bar(2) : Object "a.variable.which.does.not.exist" not found > traceback() No traceback available

Hi! Is there a way to write the information stored in the .Traceback variable to a file? When I try it with dump() ".Traceback" <- list("dump(.Traceback, file = \"Mytraceback.R\")") Or there are other ways to write this information on the disk if an error occurs? Eryk

The addition of `.traceback` in r70207 adds one more function to the call stack when invoking `traceback()`.? This changes the output of one of the examples to include the error handler call: > options(error = function() traceback(2)) > foo(2) [1] 1 Error in bar(2) : object 'a.variable.which.does.not.exist' not found 3: (function () ?? traceback(2))() at #1 2: bar(2) at #1 1:

The tracebacks are compressed into a single line because we're using PyObject_Str, but they are just about usable if not very readable. For example you would see an error like this: nbdkit: error: ./python-exception.py: config_complete: error: ['Traceback (most recent call last):\n', ' File "./python-exception.py", line 54, in config_complete\n raise_error1()\n',

A problem that I've encountered when using do.call a lot is very large stack traces, eg: f <- function(x) stop() do.call(error, mtcars) traceback() f <- function(x) browser() do.call(f, mtcars) I have hacked together my own version of traceback to fix this by limiting the length of each line to 80 characters, but I can't see any way to do something similar for browser.

On some errors during the plot of a lattice/grid graphics, there is written a message like "Error using packet 1: missing value where TRUE/FALSE needed" into the concering panel and the next panel is plotted. Which option I could use to stop the execution to have a look at the error by a traceback? Regards - Wolfram

Hello, I've written a relatively complex interconnected population model in R. When changing a certain parameter, the outputs end up containing NA's. I would like to find out, in which step the model (in form of a loop) starts to produce NA's. Does anyone know how to achieve this? Since it does not give an error I can't use the traceback() function. Thank you very much in
