When specifying an RGB colour in R, is there a strong reason not to accept 3-character HEX codes? In CSS and many other languages, a colour of "#ABC" is automatically converted to "#AABBCC", and I was wondering if R could support that as well, or if it was a conscious decision to not support it. --- http://deanattali.com [[alternative HTML version deleted]]

This request stems off a bug report I posted https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17757 where it was determined the current behaviour is as expected. To recap: when given a real file, normalizePath() always* returns the full absolute path. When given a non-existent file, normalizePath() returns a full path on Windows but it returns the input on other systems*. I'd argue that

This is related to a problem that was fixed in 2015 https://github.com/wch/r-source/commit/38ea40dcd0353af16d35296ee621338c49ae48c9 The problem then was that auto-printing by typing an object to the console would search for show() in the globalenv instead of in the methods namespace. The problem I would like to report is that it seems that when an S4 object is printed with print(), a similar

Hi r-devel If you define a function named `show` or attach a package with an exported `show` function, then printing/vieweing S4 objects breaks. This is probably because the `print` function calls `show`, which is now masked. Example: show <- function() {} > setClass("Person", slots = list(name = "character")) > tom <- new("Person", name =

Hi all Sorry for the confusing title. I noticed the following inconsistency: If i have a function that returns a named list with 2 (or more) elements, then using 'vapply' retains the names of the elements: > vapply(1:3, function(x) list("foo" = "bar", "hello" = "world"), > vector("list", 2)) [,1] [,2] [,3] foo

A slightly simpler formulation of the problem is: show <- function(...) stop("My show!") methods::setClass("Person", slots = list(name = "character")) methods::new("Person", name = "Tom") #> Error in (function (...) : My show!

I've reproduced on ubuntu and winodws with R3.4.3 When the filepath contains a tilde, the result is NA. But if the file path is expanded then the function works. Example: tools::md5sum("~/.Rprofile") returns NA tools::md5sum(normalizePath("~/.Rprofile")) returns the proper md5 Perhaps this is expected behaviour because the documentation does say NA is returned for

Hello, This is already fixed in r-devel, I think by this commit: https://github.com/wch/r-source/commit/b59a1526085d1b4375b184d35118c6fd6f003912#diff-12de104c9320556f0e99da345c6fb259 <https://github.com/wch/r-source/commit/b59a1526085d1b4375b184d35118c6fd6f003912#diff-12de104c9320556f0e99da345c6fb259> Best, Lionel > On 21 Feb 2019, at 00:07, Dean Attali <daattali at gmail.com>

If we are fiddling with normalizePath, having a way of not following symlinks (otheer than ~) would be useful as well. I had to write normalizePath2 in switchr for a specific on-the-ground need to NOT go down all he way to physical paths on a remote compute system because of how IT handled implementing constant pathing on top of swapping out hardware, and I can't imagine i'm the only

The fs[1] function `fs::path_abs()` does what I believe you were expecting `normalizePath()` to do in this case. e.g. setwd("~") normalizePath("foo/bar") #> Warning in normalizePath("foo/bar") : #> path[1]="foo/bar": No such file or directory #> [1] "foo/bar" fs::path_abs("foo/bar") #>

Just to be clear: the complaint is

I'd like to create a user interface for my R code and have only seen mostly older posts on the subject. I'm not looking for an IDE for development, but something that the end user of the software would use. So something that would involve displaying buttons, listboxes, and drop down menus to a user that will facilitate various actions. I doubt there is anything Visual Studio-like that

Isn't this exactly what Shiny is meant for? http://shiny.rstudio.com/ --- http://deanattali.com On 8 July 2015 at 11:43, vthokienj <vthokiesvt at vt.edu> wrote: > I'd like to create a user interface for my R code and have only seen mostly > older posts on the subject. > I'm not looking for an IDE for development, but something that the end user > of the software
