Dear RHelp-list, ?? I try to use the package comprehenr to replace a for loop by a list comprehension. ?I wrote the code but I certainly miss something because it is very slower compared to the for loops. May you please explain to me why the list comprehension is slower in my case. Here is my example. I do the calculation of the square difference between the values of two vectors vec1 and

Laurent, Thank you for introducing me to a package I did not know existed as I use features like list comprehension in python all the time and could see using it in R now that I know it is available. As to why you see your example as slow, I see you used a fairly complex and nested expression and wonder if it was a better way to go. As you are dealing with an interpreter doing delayed

This can be vectorized. Try ix <- seq_along(vec2) S_diff2 <- sapply(seq_len(N1-(N2-1)*ratio_sampling), \(j) sum((vec1[(ix-1)*ratio_sampling+j] - vec2[ix])**2)) On Sun, Jun 16, 2024 at 11:27?AM Laurent Rhelp <laurentRHelp at free.fr> wrote: > > Dear RHelp-list, > > I try to use the package comprehenr to replace a for loop by a list > comprehension. > > I

I would be more strong on this advice: learn to think in R, rather than thinking in Python, when programming in R. R has atomic vectors... Python does not (until you import a package that implements them). I find that while it is possible to import R thinking into Python, Python programmers seem to object for stylistic reasons even though such thinking speeds up Python also. A key step in that

I fully agree with Jeff that the best way to use ANY language is to evaluate the language in terms of not just the capabilities it offers but also the philosophy behind what it was created for and how people do things and just grok it and use it mostly in the way intended. I do that with all the languages I learn, whether for computers or humans. Bringing in something you like from another

I can't create new folder in a czech Win95 explorer on a unix using samba 1.9.18p7. The problem is that Windows exporer uses for the creation new folder a name containing characters above 128. The explorer creates new folder in a two phases: the first It creates directory named Nov<A0> slo<A7>zka and next it gives to user posibility to change this name. Crazy !!? The first phase

Dear List: I am running into a memory issue that I haven't noticed before. I am running a simulation with all of the code used below. I have increased my memory to 712mb and have a total of 1 gb on my machine. What appears to be happening is I run a simulation where I create 1,000 datasets with a sample size of 100. I then run each dataset through a gls and obtain some estimates. This works

I'm experienced in statistics, but I am a first-time R user. I would like to use R for correspondence analysis. I have installed R (Mac OSX). I have used the package installer to install the CA package.

Hi all, I have a package that is specific to a task I was repetitively using a few years ago. I now needed to run it again with new data. However I am told it was built with an older version or R and will not work. How can I tweak the package so it will run on 11.1? It was a one-off product and has not been maintained. Is there a way to "unpackage" it and repackage it to work? I

I want to bubble out of this discussion, because most of the conversation has been about merit of various tools, how much the cloud license costs, etc. In my opinion, none of this actually matters. There are much larger strategic questions that we should be talking about instead: 1) Why is LLVM special? We are a tiny community compared to the larger GitHub community - anything that makes us

Everyone, Looks like my Centos 5.0 mail server upgraded automatically last night to 5.1. It appears to have worked normally until about 16:00 CST when dovecot began to fail. I have rebooted the system to be able to use the 5.1 kernel, but dovecot still continues to fail. Has anyone else made this observation? My log entries are below Thanks in advance!!!! Greg Ennis

Hello Timo and everyone, I think on such an idea that may save me a bit of space and time: in my company we have a mailbox that holds a copy of every message that our SMTP processed. While it eats a lot of space, it saved us several times when, you may imaging, user "suddenly" deleted the most important message in his life and call our IT guys for help. The mailbox contains

?Hello everybody, I'm working on the "Use difftime for time comparison" bug (#313634). Charles directed me to the other one "Use monotonic clock for monitoring" attended to by Baruch; I believe that's very good idea, however I'd use a bit more encapsulated & general approach: 1/ I'd create an opaque timer type and its get/set/cmp/inc/dec etc interface
