Philipp Benner reported a Debian bug report against r-cran-rpart aka rpart. In short, the issue has to do with how rpart evaluates a formula and supporting arguments, in particular 'weights'. A simple contrived example is ----------------------------------------------------------------------------- library(rpart) ## using data from help(rpart), set up simple example myformula <-

Hello, I was wondering about extending FileCheck to enable creating line anchors. These are numeric variables that hold the value of the line number that where they were defined. The motivation for this comes from test cases using clang-based diagnostics which often include notes attached to source locations in different parts of the file. In order to test for the correct location of the note,

Hi Joel, That sounds like a very nice idea and definitely a direction I could get behind. However I feel that outside the use case I suggested, this functionality would only be used to compress CHECK lines that contain repeated text, not saying its a bad or good thing though. WDYT? ~Nathan On Fri, 2020-07-17 at 14:52 -0400, Joel E. Denny via cfe-dev wrote: > Hi Nathan, > > On Fri, Jul

I'm sure I'm missing something obvious here, but I can't find the solution (including in the FAQ etc.). I have a vector of names of variables like this: NRes.x.y. where x and y are numbers. I want to extract these numbers as numbers to use elsewhere. I can extract the numbers as a list of characters using strsplit(), and convert that to a data frame, e.g.:

Hi, I apologize for this often/old question. I found some hints but couldn't solve the problem so far. I have C functions (incl. the header files) as well as the R wrapper functions which I want to use for faster calculations. These functions are included in a R package. The installation process seems to be ok (no errors). I also can load the package without errors. But when I call the

Hi List, A friend of mine recently asked the same question as Heinz T?chler. Since I've already written the code I'd like to share with the list. # x is an object returned by "survfit"; # "smed" returns a matrix of 5 columns of # n, events, median, 0.95LCL, 0.95UCL. # The matrix returned has rownames as the # group labels (eg., treatment arms) if any. smed <-

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

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

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?

Hi all, after compiling R-3.4.2 on opensuse leap 42.3, make check failed. Until R-3.4.1 I never had a problem with these tests. No, the programm stops at the following line of tests/reg-tests-1d.R: > ## available.packages() (not) caching in case of errors > tools::assertWarning(ap1 <- available.packages(repos = "http://foo.bar")) > tools::assertWarning(ap2 <-

Hello, I am working on extracting data from sound recording (fee bee song of the black-capped chickadee). I obtained a two column matrix with x=time(s) and y=frequency(khz). The part of the recording that is interesting me is when the frequency is stable. Does somebody ever used a fonction that extract only constant data among a huge list of data (sample= 180000)? Thanks Thibault Grava

Dear all; I am trying to calculate volume under each polygon of a shapefile according to a DEM. when I run the code, it gives me an error as follows.

Another possible shortcut definition: assert <- function(exprs) do.call("stopifnot", list(exprs = substitute(exprs), local = parent.frame())) After thinking again, I propose to use ??? ? ? stop(simpleError(msg, call = if(p <- sys.parent()) sys.call(p))) - It seems that the call is the call of the frame where stopifnot(...) is evaluated. Because that is the correct context, I

A private reply by Martin made me realize that I was wrong about stopifnot(exprs=TRUE) . It actually works fine. I apologize. What I tried and was failed was stopifnot(exprs=T) . Error in exprs[[1]] : object of type 'symbol' is not subsettable The shortcut assert <- function(exprs) stopifnot(exprs = exprs) mentioned in "Warning" section of the documentation similarly fails
