...oblem with no clue. My version is 2.5.1. Below is a function to check if a given date is a valid date to a given date function object. It uses try (also tried tryCatch but with same problem). When given an invalid date, I am hoping try will generate en error message which would be picked up by the geterrmessage and thus expecting a false result. but this is not the case when it is inside a function. However, if simply run the body of function, the ret is indeed a false value. Why are they different? Many thanks is.Date= # adate: a scalar value # fun: the date function object # format: the designated d...

....txt, it executes: source(?USERCODE.txt?) If that file is not present, the script executes without a problem. There might be syntax errors in USERCODE.txt; therefore, the code above is embedded in a try command: try(source(?USERCODE.txt", local=T), silent=T) followed by: ERRORMESSAGE <- geterrmessage() For unclear reasons, an earlier command is yielding an error message: unused argument (\"\\n\") Despite identifying the exact source of that error, I can?t fix it (and it is of no consequence). Ideally, I would like to clear out the pre-existing error message immediately before the...

Only the default error handler puts the error message in a buffer where it can be retrieved with geterrmessage. try() replaces the default error handler. Either look at the value returned by try() or use tryCatch with conditionMessage.

Hi R-helpers, I am using rpart package for decision tree using R.We are invoking R environment through JRI from our java application.Hence, the result of R command is returned in REXP and we use geterrMessage() to retrieve the error. When we execute the following command, cnr_model<-rpart(as.factor(Species)~Sepal Length+Sepal Width+Petal Length, method="class", parms=list(split="gini",prior=c()), control=rpart.control(minsplit=2, na.action=na.pass,cp=0.001,usesurrogate=1,maxsur...

I am looking for a way to get a warning message immediately after an evaluation within a function. To get error messages you can use geterrmessage(). But I found no function that allows me to check for warnings. Five years ago this questions has been posted but I haven't found any answer. Thanks for any help. Peter Wolf ------------ For illustration purpose a simple example follows: you can get warnings after an error occured or af...

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back an use try()/tryCatch(). Thanks, Henrik

Dear All, I'm using "reg.finalizer" in a function that is to be called in R scripts to do some cleanup on success. I have not found a way to run the function only if the script run without errors, so when the exit code is expected to be 0. What I've tried is checking "geterrmessage()", but unfortunately it's not perfect: if an error was handled with eg "tryCatch" previously, that message still shows up there. Is there any better way of figuring out in "reg.finalizer" or ".Last" if the session run OK or exiting with !0 exit code? Thank...

...e completely isolated from the mechanism that is adding this extra diagnostic information. Is this actually possible?

...ailable I try to use tryCatch(...) instead, I could get the stack traceback (using the finally), but the R program stop. 2. My goal -------------------- All I need is to prevent a error to stop a program (like try() does), print the traceback just after the try(....), and get the error message (geterrmessage()). 3. Question ------------------- A) stack traceback is not available when error ouccured in a try is a normal behavior ? B) Do you have any sugestion to fill my goal ? C) If not is it a good idea to investigate around withRestarts(expr, ...) ? Best regards PS : My R Version 1.8.1 (2003-1...

I'm trying to get a translation of some Splus code going. My problem is with the S-plus get.message() function not existing in R. Is there a replacement or alternative? ErrorHandler.func<-function() { cat("app.terminated\n"); cat(paste("err.fatal",get.message(),"\n",sep="")); dump.calls(); } options(error=ErrorHandler.func)
