...onder 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 non-interactively; frames dumped, use debugger() to view" Thanks Jeff

No. There are already many ways to influence the way the default error handler prints information about errors, mstly via options(). In particular you may want to look at entries in ?options for show.error.locations showErrorCalls showWarningCalls and adjust your options settings accordingly.

I would like to have an automatic traceback printed on error. Is there a way to do this? options(error=traceback) seems to print the previous error, not the current error. I'm guessing this is because the traceback is not set until the error handler is done running. > options(error=traceback) > stop("1") Error: 1 No traceback available > stop("2") Error: 2 1:

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?

Hi Duncan ? Wonderful. Thank you. Bug or no bug, I think it would be a huge improvement for user-friendliness if R printed the last line by default *every time* a script dies. Most computer languages do so. Should I file it as a request for improvement to the R code development team? Maybe R can be improved at a very low cost to the development team and a very high benefit to newbies.
