similar to: Capturing the error information

Is there any way to include warnings in the output from capture.output? eg: a <- capture.output(warning("test")) all.equal(a, "Warning message: \n test ") Conceptually, this seems like redirecting stderr to stdout, or somehow changing warning to simple print it's output. I've had a look at tryCatch and using a warning handler, but this terminates execution at the

tryCatch() is good for catching errors but not so good for warnings, as it does not let you resume evaluating the expression that emitted the warning. withCallingHandlers(), with its companion invokeRestart(), lets you collect the warnings while letting the evaluation run to completion.

So after about 4 hours struggling with Try and TryCatch I am throwing in the towel. I have a more complicated function that used logspline through iterative distributions and at some point the logspline doesnt function correctly for some subsets but is fine with others so I need to be able to identify when the error occurs and stop curtailing the distribution and I think this Try or TryCatch

1. I did not attempt to sort through your voluminous code. But I suspect you are trying to reinvent wheels. 2. I don't understand this: "I've failed to find a solution after much searching of various R related forums." A web search on "error handling in R" **immediately** brought up ?tryCatch, which I think is what you want. If not, you should probably explain why it

Hello all, I'm trying to setup a simple construct that will email me all errors, warnings, and output of a sample R script. My initial thought was to use sink() and tryCatch around the script such that at the end of the script any output would be mailed to me, i.e.: sinkFile <- tempfile() sink(sinkFile) tryCatch({ [R script]}, finally = { sink() if (length(readLines(sinkFile)))

I don't want to return a value, I want to interrupt the computation, that's why I need to re-throw . But before getting back to the user I want to run some cleanup code. G.

Hello all, I'm a beginner in R working on a script that will produce a set of models (linear, polynomial and logistic) for each location in a dataset. However, the self-starting logistic model often fails - if this happens I would like to just skip to the next iteration of the loop using tryCatch. I've looked at a few examples and read the help file, but didn't understand tryCatch

Dear all, For an open-source project that I'm working on (1), which uses R for all its heavy lifting but includes a wrapper shell script, I was hoping to find a way to capture all warnings (and, in fact, errors too), and handle them in my own way. I realise I can do this for a single expression using something like: > f <- function(w) print(w$message) >

Anyone knows a way to re-throw a caught interrupt condition, so that it behaves just like the original one? I.e. no error message is printed, but the execution is stopped of course. With just calling stop in the error handler, it prints the error message, or, if there is no error message (like in the original interrupt condition), another error happens. tryCatch(Sys.sleep(100), interrupt =

The following example involves a function whose on.exit() expression both generates an error and catches the error. The body of the function also generates an error. When calling the function wrapped in a tryCatch, should that tryCatch's error function be given the error from the body of the function, since the one from the on.exit has already been dealt with? Currently the outer tryCatch
