Does signalCondition() only work within try-catch blocks? I expected: testSignal <- function() { error <- simpleError("An error!") signalCondition(error) } to do the same thing as testStop <- function() { error <- simpleError("An error!") stop(error) } but testSignal returns NULL without throwing an error. Have I misunderstood something?

Hello, I would like to establish top level condition handlers and restarts, so that I don't explicit calls to withCallingHandlers and withRestarts in many places: For example : > customError function( message ){ err <- simpleError( message ) class( err ) <- c( "customError", class( err) ) err } > withCallingHandlers( { signalCondition(customError(

Hi, I'm looking for a way to generate a "full stop" that will not be caught by signal handlers, cf. .Internal(.dfltStop(msg, call)). RATIONALE: In the R.oo package I have throw() which (leaving out some details) basically does what stop() does but appends a stack trace string to the error message that shows up at the R prompt. Example: bar <- function() throw("A foo

The below code snippet gives a single warning: Warning message: In cat(s, file = tempfile()) : invalid char string in output conversion when n <= 10001, whereas with n >= 10002 it appears to be generating the same warning in an infinite loop in the call to cat(). n <- 10002L r <- raw(length = n) r[] <- charToRaw(" ") r[length(r)] <- as.raw(0xa9) s <-

The suppressMessages and suppressWarnings functions currently suppress all the message or warnings that are generated by the input expression. The ability to suppress only specific messages or warnings is sometimes useful, particularly for cases like file import where there are lots of things that can go wrong. Suppressing only messages that match a regular expression has rightly been rejected

Dear expeRts, I am struggling with warning/error handling. I would like to call a function which can produce either a) normal output b) a warning c) an error Since the function is called several (thousand) times in a loop, I would like to proceed "quietly" and collect the warnings and errors [to deal with them at a later point]. I have seen constructs with tryCatch (which can

I am extending a DBI connection by setClass("TSPostgreSQLConnection", contains=c("PostgreSQLConnection","TSdbOptions")) but the first time I use this I am getting a warning when it tries to coerce the TSPostgreSQLConnection to a PostgreSQLConnection. After the first use the warning stops, but the first warning is causing me problems when I do automatic checks

Hello, I am fairly new to using R and am trying to install it on my Linux machine, running Scientific Linux. I get through running 'configure' and 'make' OK, but when I run 'make check', I get the following error: make check make[1]: Entering directory `/home/gruchti/Programs/R-2.7.0/tests' make[2]: Entering directory `/home/gruchti/Programs/R-2.7.0/tests'

Conditions have classes and the condition system is designed around the idea that classes would be used for this sort of thing. That is already how tryCatch and withCallingHandlers discriminate the conditions to handle. Designing and implementing a condition class hierarchy to support this is indeed the hard/tedious part.

Hi, I'm trying to learn how to use the tryCatch condition system and am confused about the behavior when I set the call arg of a simpleCondition. I want to catch an error if it meets a certain criteria and otherwise reraise it. I want the error message to indicate the function in which the error occured (and not mention tryCatch). Wanted: > g("foo") ## error caught

I'm confused by the page documenting tryCatch and friends. I think it describes 3 separate mechanisms: tryCatch (in which control returns to the invoking tryCatch), withCallHandlers (in which control goes up to the calling handler/s but then continues from the point at which signalCondition() was invoked), and withRestarts (I can't tell where control ends up). For tryCatch the docs say

The internal code does more or less signalCondition(e) ## allows for (another) handler cat("\n") ## cleans up console invokeRestart("abort") ## jump to 'abort' restart if not handled [for back compatibility it also runs the error option code if that is set, but that may go away eventually].

Thank you for the introduction to these recent changes, Martin. I think this was the second time I ran "make check" on that platform (Raspberry Pi 32-bit), and the first time (some months ago) it worked fine. So, that makes it kind of "suddenly", although I must say that my use of "make check" is very irregular. I compared code before and after the split you are

Hi, I am facing one problem of fetching R warning messages in Java Code using Rserve. It is easier to trap R Error messages by using catching RSrvException. I came to know one way of fetching R Warning messages, i.e. using "withCallingHandlers", below is my Java Program, which uses withCallingHandlers of R : import org.rosuda.JRclient.*;
