Thanks all, I don't know either (for the moment). It's all in the design phase still. Generally, I would also like to keep specific functions in specific packages, if at all possible.

Great spot, thanks Mark. This really ought to appear somewhere in the ?Quotes help page. Having a warning under Windows might be nicer behaviour than silently returning the wrong value too.

This doesn't work, because 1. all.equal does *not* return FALSE. Use of isTRUE or identical(., TRUE) is required if you want a boolean. 2. all.equal compares two objec...

This question is more out of curiosity than a complaint or suggestion, but I'm just wondering. The behavior of R on calculations that result in NaN seems a bit inconsistent. # this is expected: > 0/0 [1] NaN # but this gives a warning > sin(Inf) [1] NaN Warning message: In sin(Inf) : NaNs produced # and this again does not > exp(NaN) [1] NaN Conceptually, I like to think that R

Dear R-developers, In the 'lm' documentation, the '-' operator is only specified to be used with -1 (to remove the intercept from the model). However, the documentation also refers to the 'formula' help file, which indicates that it is possible to subtract any term. Indeed, the following works with no problems (the period '.' stands for 'all terms except the

Hi, In some cases the number of arguments passed as ... must be determined inside a function, without evaluating the arguments themselves. I use the following construct: dotlength <- function(...) length(substitute(expression(...))) - 1L # Usage (returns 3): dotlength(1, 4, something = undefined) How can I define a method for length() which could be called directly on `...`? Or is it an

...es exactly what you are asking for. Before that, I don't know of an easy way to get the length without evaluation via R code. There may be one I'm not thinking of though, I haven't needed to do this myself.

@Gavin: My aim was to point out that the ability to mix developer-facing documentation with user-facing documentation is not a good reason to want to support md. I agree with Duncan that links to within a package would be useful (not sure if NEWS.Rd supports this). I'm not so convinced that package authors that do not even add a plain text NEWS file will create a NEWS.md file. Adding

Agreed that's it's rounding error, and all.equal would be the way to go. I wouldn't call it a bug, it's simply part of working with floating point numbers, any language has the same issue. And while we're at it, I think the function can be a lot shorter: .is_continous_evenly_spaced <- function(n){ length(n)>1 && isTRUE(all.equal(n[order(n)], seq(from=min(n),
