I have a data set that looks like this: dene <- data.frame(length = c(35,32,33,34,41,40,46,35,41,40,45,36,38,37,39,40,42,42,42,43,44), sex=c(1,1,1,1,2,2,2,1,2,2,2,1,2,2,2,2,2,2,2,2,2)) I would like to plot the density (frequency of occurrence) of each length class but I want to have different colors for sex. I used the following: library(...

...ngth <- 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 intention to extend the base length() function to accept ellipses? Regards, Denes

...ubstitute(list(...))[-1L] ` I would like to know if: 1) substitute(...()) is a trick or a feature in the language; 2) it will be supported in the future; 3) when (in which R version) it was introduced. A hint on where to look for the machinery in the R source would be also appreciated. Regards, Denes

...a feeling all of this is just return() performing correctly though. If there are already R CMD CHECK checks for this kind of thing (I wasnt sure but I'm hearing from others there may be/are) that may be (and/or may need to be) sufficient. ~G On Fri, Nov 20, 2020 at 3:27 PM D?nes T?th <toth.denes at kogentum.hu> wrote: > Or even more illustratively: > > uneval_after_return <- function(x) { > return(x) * stop("Not evaluated") > } > uneval_after_return(1) > # [1] 1 > > On 11/20/20 10:12 PM, Mateo Obreg?n wrote: > > Dear r-developers- >...

Thank Denes for the clarification, glad to see my package got one citation from my own question:) Also, thank Benjamin for sending many useful documents. Actually, the question is related to the SharedObject package that Benjamin has pointed to. I wanna avoid sharing an object that has already been shared, s...

Benjamin, You happened to send a link which points to the OP's own package :) I think Jiefei would like to know how one can "officially" determine if an arbitrary ALTERP object belongs to a class that he owns.

...not prepared for those differences. (To learn more, read the data tables vignette.) Tibbles (as produced by unnest in my previous response) are not data tables either, but they behave much more like data frames than data tables do.
