Thanks Brodie, that's some nice detective work. If someone wanted to grant me access to Bugzilla, I'll be happy to post the bug and patch there (with your permission Brodie?) and help this bug get fixed. Mike.

I've found over time that R documentation that comes off as terse at first blush is usually revealed to be precise, concise, and complete on close reading.? I'm sure this is also true of `?findInterval`, but for whatever reason my brain simply refuses to extract meaning from it. Part of the problem may be that we interact with the function via a compressed form of the bounds of the

Notice also Additionally, since you're implementing a "mean" function you are testing against R's mean, you might want to consider that R uses a two-pass calculation[1] to reduce floating

Hi there, using cbind with a numeric and raw argument produces an incorrect result. I've posted some details below, kind regards, Mike. e.g. > cbind(0, as.raw(0)) [,1] [,2] [1,] 0 6.950136e-310 A longer example shows that the result is not a rounding error, is not consistent, and repeated applications get different results. > cbind(0, as.raw(1:10))

I think there is a memory bug in `substr` that is triggered by a UTF-8 corner case: an incomplete UTF-8 byte sequence at the end of a string.? With a valgrind level 2 instrumented build of R-devel I get: > string <- "abc\xEE"??? # \xEE indicates the start of a 3 byte UTF-8 sequence > Encoding(string) <- "UTF-8" > substr(string, 1, 10) ==15375== Invalid read of

I noticed some problems that cropped in the latest versions of R-devel (2016-11-08 r71639 in my case) for one of my packages. I _think_ I have narrowed it down to the changes to what gets byte-compiled by default. The following example run illustrates the problem I'm having: compiler::enableJIT(0) fun <- function(x) local(as.list(parent.frame(2))) fun(1) ## $x ## [1] 1 ##

One of the things I often wish R would work with: When calling print() explicitly --- as I do not so rarely, e.g., specifying digits = <nd> --- it sometimes seems awkward that from the printing options() , one can specify 'digits' and it has default digits = NULL which is documented to be equivalent to digits = getOption("digits"), but one cannot specify 'width'

Luke, thanks for considering the issue.? I would like to try to separate the problem into two parts, as I _think_ your comments address primarily part 2 below: 1. How can we avoid significant and possibly crippling ?? stalls on error with these non-standard calls. 2. What is the best way to view these non-standard calls. I agree that issue 2. requires further thought and discussion under a

The build system rolled up R-4.0.2.tar.gz (codename "Taking Off Again") this morning. The list below details the changes in this release. You can get the source code from http://cran.r-project.org/src/base/R-4/R-4.0.2.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course. For the R Core Team, Peter Dalgaard

The addition of `.traceback` in r70207 adds one more function to the call stack when invoking `traceback()`.? This changes the output of one of the examples to include the error handler call: > options(error = function() traceback(2)) > foo(2) [1] 1 Error in bar(2) : object 'a.variable.which.does.not.exist' not found 3: (function () ?? traceback(2))() at #1 2: bar(2) at #1 1:

Currently S3 objects nested in generic vectors cause the tag buffer to be reset.? This feels sub-optimal for those objects that don't have a print method: > list(a=list(b='hello')) $a $a$b???????????????? ### <<<< notice "$a$b" [1] "hello" > list(a=structure(list(b='hello'), class='world')) $a $b?????????????????? ###

We also have a few other suggestions and wishes about backtrace storage and display on the one hand, and display of constructed calls on the other hand. Perhaps it would be better to open a different wishlist item for traceback() to keep the discussions focused? FWIW I think deparsing backtraces lazily is a great idea. Displaying 1 line per call by default in interactive sessions, while being

I'm still uncomfortable at having to call `options` in my package `diffobj` to set output width. Adding a few more cents: It might be worth considering "who" should be allow to control the 'width' argument. In
