I'm attempting to reflect the information for use with corresponding fields in GUI (in a different package), to provide default values, argname as key for UI label lookups, etc. So I want something much more like the formals of the implementation: { "object", "method": c("median", "vs", "tukey"),

Hi I had a hard-to-find bug in some of my code the other day, which I eventually traced to my misusing of sweep(). I would expect sweep() to give me a warning if the elements don't recycle nicely, but X <- matrix(1:36,6,6) sweep(X,1,1:5,"+") [,1] [,2] [,3] [,4] [,5] [,6] [1,] 2 9 16 23 30 32 [2,] 4 11 18 25 27 34 [3,] 6 13 20 22

...48 kbps compared to 96kHz Vorbis at 31kbps is about double the size and it sounds even worse (than Vorbis) (there is a lot of noise in the lower frequencies when a low frequency tone is being played).

I am having a hard time understanding just what 'sweep' does. The documentation states: Return an array obtained from an input array by sweeping out a summary statistic. So what does it mean "weeping out a summary statistic"? Thank you. Kevin

Hi, I would like to use sweep to "sweep out" proportions and confidence intervals for an array, however when I supply a function which returns a string (containing something like "9% (3-18%)") I get back a list instead of an array, here is a simplified example: # example showing that sweep does not return an array with same dimensions as STATS as advertised

Hi Jean-Marc and others, I put Speex support in Sweep (a sound editor) yesterday, and had some fun with it :) I'd like to get some feedback before releasing it publically. I'm not really used to speech codecs (I work more with music) but I've been quite impressed at the file size and quality (especially when you hear what I did with some of the sample files ;) I didn't have any

At this point I would just due: formals(body(method)[[2L]]) At some point we need to figure out what to do with this .local() confusion.

Agreed, definitely. The current hack is to avoid re-matching arguments on method dispatch, so a fix would need to be fairly deep in the

The call to sweep in this function which was working in 0.62.2 is giving me trouble in 62.3: prcomponents <- function(x, center=TRUE, scale=TRUE, N=nrow(x)-1) {if (center) center <- apply(x,2,mean) else center <- rep(0, ncol(x)) if (scale) scale <- sqrt(apply(x,2,var)) else scale <- rep(1, ncol(x)) s <- svd(sweep(sweep(x,2, center),2, scale,

Would you please clarify your exact use case?

I decided to do a direct comparison of transpose and sweep. library(microbenchmark) NN <- matrix(c(1, 2, 3, 4, 5, 6), nrow = 2, byrow = TRUE) # Example matrix lambda <- c(2, 3, 4) # Example vector colNN <- t(NN) microbenchmark( sweep = sweep(NN, 2, lambda, "/"), transpose = t(t(NN)/lambda), colNN = colNN/lambda ) Unit: nanoseconds expr min lq

The intermediate opus file already contains only the first of the two repeating sweeps. After around 50s, there is silence. The resulting wav file too then, obviously. As far as I can tell (see the attached spectrograms), the sound dies out around the point the freq reaches 12kHz.

Hi all, To get wider visibility, build a broader consensus and address concerns on this topic, I'm again raising this as an RFC. This is a proposal to change the rule for variable names from CamelCase to camelBack _really this time_. Background: This has been proposed several times on this mailing list in the past. Most recent one was by Michael Platings in February this year [1], and there

A friend of mine just got bitten by the fact that sweep() will happily sweep out a STATS vector of an arbitrary length -- even one whose length is not a divisor of any of the margins -- without complaining. I know the answer to this could be "well just don't do that", but it's easy to make a mistake in which margin you're sweeping ... What would R-core think of the
