Re: [R] the opposite of pluck() in purrr

As noted, this is not the place to ask about dplyr but the answer you may want is perhaps straight R. If you have a list called weekdays and you know you o not want to take the fifth, then indexing with -5 removes it: > weekdays <- list("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat") > weekdays[

Re: [R] the opposite of pluck() in purrr

tidyverse is an RStudio ecosystem of packages -- it is not part of R's "standard" package distro, so as the posting guide linked below says: "For questions about functions in standard packages distributed with R (see the FAQ Add-on packages in R

[R] the opposite of pluck() in purrr

I've just learned about pluck() and chuck() in the purrr package. Very cool! As I understand it, they both will return one element of a list, either by name or by [[]] index, or even "first" or "last" I was hoping to find a way to return all *but* one specified element of a list. Speaking loosel

Hi RosalinaZakaria, Talk about using a sledgehammer to crack a nut. In your example the two objects are character vectors. How about: dt_comb1gd <-paste0(dtpaigd,dtpmgd) Jim On Fri, Nov 19, 2021 at 2:15 AM ROSLINAZAIRIMAH BINTI ZAKARIA . wrote: > > Dear all, > > I try to merge two columns consi

Re: [R] Merge column with characters

Hello, Use an index giving the "" positions. i <- nchar(dtpmgd) == 0L dtpmgd[i] <- dtpaigd[i] Or, in one line, dtpmgd[nchar(dtpmgd) == 0L] <- dtpaigd[nchar(dtpmgd) == 0L] Hope this helps, Rui Barradas Às 07:02 de 18/11/21, ROSLINAZAIRIMAH BINTI ZAKARIA . escreveu: Dear all, I try t

I haven't been able to get remote desktop working, I suspect it's disabled for security reasons. Any other thoughts/suggestions? On Thu, Nov 18, 2021 at 2:22 AM Mark Fowler wrote: > Hi, > > > > This issue bears some similarity to a problem I’ve been experiencing over > the last few days. R 4.0.

Re: [R] Help with strange RGui behavior? Will not consistently run source.

HI Stephen, The reason I suggested the test was that I had a real flakey and annoying GUI problem a couple of years ago. It had to do with selection by mouse etc. The IT group could not reproduce the problem (when they connected remotely) and I realized that when I worked from home I also avoided t

I have not tried that. I'm not certain if I have the permissions for remote desktop, but I will find out and give it a shot if possible. On Wed, Nov 17, 2021, 12:04 PM Eric Berger wrote: > Hi Stephen, > Does the problem still occur if you connect remotely to your computer from > a different comp

Re: [R] How to create a proper S4 class?

From my example, as(employees, "People") more general coercion is possible; see the documentation ?setAs. From your problem description I would have opted for the solution that you now have, with two slots rather than inheritance. Inheritance has a kind of weird contract when using another
