I work on a fairly large website that uses Ruby 1.8.6 and Rails 1.2.3. We cannot upgrade as it will hopelessly break our code. We are working on a new version in Java but for the next year at least we are stuck with the legacy system. We use the latest version of Postgresql for the database using the postgres-pr gem. I am attempting to implement cron tasks within the system using Rufus Scheduler,

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:

For whatever my 2c are worth I think this would be nice.? I'm still uncomfortable at having to call `options` in my package `diffobj` to set output width. And since the topic is here, what about `show`?? Feels like it should accept `...` so that it too could be given some set of standard or non standard parameters, including `width`. Happy new decade.

...pen to providing a prose translation, but putting that in the details? If so, it would be useful to get feedback on what parts of the prose I proposed are imprecise enough to be incorrect/incomplete for some corner case. Finally, would it make sense to move this discussion to bugzilla? Best, Brodie.

...like my wrapped-text columns to be nice and even, which is why I'm proposing the patch.? Posting here in case others are interested in the issue. This doesn't do any grapheme computations so it won't work with combining emoji, but should still be a step in the right direction.

Re ENSURE_NAMEDMAX, I am unsure but think this happens in (src/eval.c at 492): static SEXP forcePromise(SEXP e) { ??? if (PRVALUE(e) == R_UnboundValue) { ??? /* ... SNIP ...*/ ??? val = eval(PRCODE(e), PRENV(e)); ??? /* ... SNIP ...*/ ??? SET_PRSEEN(e, 0); ?? ?SET_PRVALUE(e, val); ?? ?ENSURE_NAMEDMAX(val);???????????????? <<<<<<< HERE ?? ?SET_PRENV(e, R_NilValue); ??? } ???

...those more knowledgeable of the inner workings of S4. I ran `make check-all` on a recent version of R-devel with the patch applied, and everything came back OK. However, I'm guessing there isn't much natural testing of unloading packages, so this probably requires extra scrutiny.

As per `?intToUtf8`, and in the comments to `valid_utf8`[1], R intends to prevent illegal UTF-8 such as UTF-8 encoded UTF-16 surrogate pairs.? `R_nchar`, invoked via `base::nchar`, explicitly validates UTF-8 strings[2], but allows the surrogate: ??? > Encoding('\ud800') ??? [1] "UTF-8" ??? > nchar('\ud800')? // should be an error ??? [1] 1 The problem manifests

...t to understand the documentation should venture to re-write it. Nonetheless I attach a proposed alternate version in the hopes that someone who clearly understand the original might use or adapt parts of it to make `?findInterval` more accessible to those comprehension-challenged like me. Best, Brodie

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?????????????????? ###

...7.31. > > You just can't trust == on FP operations. 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 point precision error.

...those probably push the envelope in this area.? There only one failed with 2,613 passing.? The failed one is for a deprecated function that was specifically checking for the repeated `evalq` contexts[7]. I also attach a document with additional examples and commentary for those interested.

...as is the case with `traceback()`, or in `print(sys.calls())` and similar. I attach a patch that does this.? I have run some basic tests and `make check-devel` passes. I can file an issue on bugzilla if that is a better place to have this conversation (assuming there is interest in it).

...lution at hand, especially since the complete deparse of large objects likely serves no purpose in this case. Obviously, if storing the actual calls instead of their deparsed equivalents in .Traceback causes problems I'm not anticipating, then that's different.? Is that the case? Best, Brodie.
