Hi All, I'm trying to use the "sample" function within a loop where the vector being sampled from (the first argument in the function) will vary in length and composition. When the vector is down in size to containing only one element, I run into the "undesired behaviour" acknowledged in the ?sample help file. I don't want sample(10,1) to return a number from

> Why are you using a stereo file > containing the same sweep in both channels > and then downmixing to mono? When I first tried encoding at a higher bitrate, I needed to test the different behavior of the "mid" (l+r) and "side" (l-r) channels. That's why I made the first sweep identical on both the left and the right channel (i.e. "side" is silent)

Hello all, I create the following matrix: m <- matrix(1:20, nrow = 10, ncol = 2) which looks like: [,1] [,2] [1,] 1 11 [2,] 2 12 [3,] 3 13 [4,] 4 14 [5,] 5 15 [6,] 6 16 [7,] 7 17 [8,] 8 18 [9,] 9 19 [10,] 10 20 Then, I want to remove randomly 2 rows among the ones where m[,1]<8 and m[,2]>12 I suppose the

Dear list, I came across a behavior that IMHO is somewhat undesired when calling '$field()': If the field name whose value you're trying to get is *not* a valid field of the Reference Class, then R doesn't stop there with an error, but scans through all enclosing environments/frames. The result is something similar to calling '|get(<objname>, inherits=TRUE)|'

Full_Name: Michael Chajewski Version: 2.9.0 OS: Windows XP Submission from: (NULL) (150.108.71.185) I was programming a routine which kept reducing the array from which a random sample was taken, resulting in a single number. I discovered that when R attempts to sample from an object with only one number it does not reproduce/report the number but instead chooses a random number between 1 and

Hi all, I've been working on improving R's optim() command, which does general purpose unconstrained optimization. Obviously, this is important for many statistics computations, such as maximum likelihood, method of moments, etc. I have focused my efforts of the BFGS method, mainly because it best matches my current projects. Here's a quick summary of what I've done: *

I was wondering if it was possible to get a Samba server that was acting as an AD member server to also be able to authenticate local users, or is stuck just serving AD users? -- Aaron Clausen mightymartianca at gmail.com

Hi all, I wrote a symbollic differentiation function in R, which can be downloaded here: http://www.econ.upenn.edu/~clausen/computing/Deriv.R http://www.econ.upenn.edu/~clausen/computing/Simplify.R It is just a prototype. Of course, R already contains two differentiation functions: D and deriv. However, these functions have several limitations. They can probably be fixed, but

Hello! s<-"start"; e<-"end" middle<-as.character(c(1,2,3)) I would like to get the following result: "start 123 end" or "start 1 2 3 end" or "start 1,2,3 end" How can I avoide this (undesired) result: paste(s,middle,e,sep=" ") Thank you! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com

Hi, I have just noticed an undesired behavior when using rsync when disk quota is exceeded. I do not know how to avoid it (or maybe it can be considered as a bug). The following is a scenario that leads to the undesired behavior: 1) I normally execute two following commands to synchronize folders between a local host and a remote host: rsync -aCPvu --existing <dir1>

Hello R-devel community, I posted a new R 4.0.1 behaviour to stack overflow (https://stackoverflow.com/questions/62327810/inconsistent-error-handling-of-function-and-s4-generics-on-r-4-0-1), where I think it is an undesired or unexpected change in 4.0.1. Attributes of errors seem to be lost or obscured when encountered in an S4 generic context. An example of this being undesirable comes in shiny

Hi all, I wrote a function called relist, which is an inverse to the existing unlist function: http://www.econ.upenn.edu/~clausen/computing/relist.R Some functions need many parameters, which are most easily represented in complex structures. Unfortunately, many mathematical functions in R, including optim, nlm, and grad can only operate on functions whose domain is a vector. R has a

In preparing to answer a question about some yum undesired behavior, I wanted to reference fastest mirror info, but when I went to https://wiki.centos.org/PackageManagement/Yum/FastestMirror I find all the text has been squished to the right hand side of the page and made 1 word wide all the way down. The https://wiki.centos.org/FrontPage looks similar but perhaps it is a little better? Or is

Hi all, As long as I've used R, add=TRUE hasn't worked in contexts like this: f <- function(x) x^2 X <- seq(0, 1, by=1/4) plot(f, col="blue") plot(X, f(X), col="red", type="l", add=TRUE) I attached a fix for version 2.6.2.

Hi all, Over the past 10 years, there has been some discussion and several patches concerning keystroke timing being revealed by the timing of openssh packet network transmission. The issue is that keystroke timing is correlated with the plaintext, and openssh users expect their communications to be kept entirely secret. Despite some excellent ideas and patches, such as Jason Coit's

This post about length 1 offsets on R help seems to have been ignored (sorry deleted original email - is there a way to continue thread in this case?) https://stat.ethz.ch/pipermail/r-help/2009-February/189352.html It does seem to be a bug, in that glm does not behave as documented. In fact the same bug applies to lm as well. I don't think the suggested fix works though - Y isn't
