I was building a package that uses the new generic @ and kept having errors with ?roxygen2? documentation. ?roxygen2? generated NAMESPACE added `@.newclass` as a newly exported function, not as a S3method. At first I thought this must be a bug...

In specific cases fligner.test() can produce a small p-value even when both groups have constant variance. Here is an illustration: fligner.test(c(1,1,2,2), c("a","a","b","b")) # p-value = NA But: fligner.test...

This issue might go deeper - I was not successful in passing R CMD checks for the usage files. R CMD check kept showing errors for `@` declarations, even thou they were identical to `$` declarations (which passed fine). Seems like the usage...

Hello, I also want to report 2 missed cases of stringsAsFactors=TRUE in base: 1. grid.expand() still uses hard stringsAsFactors=TRUE in its arguments. 2. as.data.frame.table() also keeps factors after conversion from table. >>>>>> Duncan Murdoch >>>>>> on...

Hello, I recently stumbled on an unusual behaviour of any() and all() and have been adviced from StackOverflow to share it here [1]. df1 <- data.frame(A=TRUE, B=FALSE) df2 <- data.frame(A=1, B=0) > any(df1) Error...

I was calling table() on some long logical vectors and noticed that it took a long time. Out of curiosity I checked the performance of table() on different types, and had some unexpected results: C <- sample(c("yes", "no"), 10...

Hello, I have stumbled upon a few cases where the behaviour of naming and subsetting in matrices seems unintuitive. All those look related so wanted to put everything in one message. 1. Why row/col selection by names with NAs...

Hello, Today I was investigating ks.test() with two numerical arguments (x and y) and was left a bit confused about the policy behind handling ties. I might be missing something, so sorry in advance, but here is what confuses...

Hello, Writing to share some things I've found about wilcox.test() that seem a a bit inconsistent. 1. Inf values are not removed if paired=TRUE # returns different results (Inf is removed): wilcox.test(c(1,2,3,4...

Ah, you are correct, my bad and apologies. I forgot that table is only for available methods, not for available generics. KK. > On Apr 30, 2023, at 4:49 PM, Kurt Hornik <Kurt.Hornik at wu.ac.at> wrote: > >>>>>> Karolis...

But this might require a more detailed investigation. For example I just noticed that even with the patch `@` is still not listed in .S3_methods_table(). KK. > On Apr 29, 2023, at 4:44 PM, Karolis Koncevi?ius <karolis.koncevicius...

So I tried adding Infinity support for all cases. And it is (as could be expected) more complicated than I thought. It is easy to add Inf support for the test. The problems start with conf.int=TRUE. Currently confidence...

Hello Kurt, With r84341 it now works on my side. Warm regards, Karolis K. > On Apr 29, 2023, at 1:24 PM, Kurt Hornik <Kurt.Hornik at wu.ac.at> wrote: > >>>>>> Karolis Koncevi?ius writes: > > Can you pls try again...

A more concrete example in order to correct my vague messages below. Writing an R package that uses `@` and `@<-` as S3 generics. Line from manual pages in .Rd files: \method{@}{newclass}(object, name) <- value Throws this error during R CMD...

Thank you for such a quick reply, here are some points that I think might have been missed: > I would state the question the other way : why are NAs integer indices allowed? > In my experience, they are sometimes useful but...

Thank you for such a quick reply, Gabriel, I am not too familiar with the package tools, so cannot speak too confidently, but below is how I see the issue currently. The issue is not for external packages to rely...

I see I am too late to comment :) But commenting after the fact, just wish to say that I like the changes. Specially the mentioning of "exact" in the test name. Floating point prevision is very nicely implemented too. My...

Thank you for a fast response. Nice to see this mailing list being so alive. Regarding Inf issue: I agree with your assessment that Inf should not be removed. The code gave me an impression that Inf values were intentionally...

Thank you for responding, and so quickly at that. Yes, I do understand that this is a floating point issue. However, since wilcox.test() works on ranks this might be a bit dangerous in my opinion. Maybe more so than...
