Dear List, I'm struggling with the signature writing cbind/rbind functions for a S4 class. First of all, I'm very happy that it is now possible to dispatch on ... I follow the example for "paste" in ?dotMethods, which works as far as this: ### start example setClass ("cbtest", representation = representation (data = "data.frame"),

Dear all, I work with (vibrational) spectra: some kind of intensity (I) over frequency (nu), wavelength or the like. I want to do fourier transform for interpolation, smoothing, etc. My problem is that the spectra are often irregularly spaced in nu: the difference between 2 neighbouring nu varies across the spectrum, and data points may be missing. Searching for discrete fourier transform

Dear List, I recently stumbled over the possibility and need to specifiy % \VignetteDepends{} in my vignettes. I did not know about this, and I notice that it is not mentioned in the R-extensions manual section "Writing package vignettes". I have some questions with regards to that: - would it be possible to include into the section "Writing package vignettes" some hint

Dear all, I just noticed, that prompt () looses backticks that protect default arguments: f <- function (FUN = `*`) {} cat (prompt (f, NA)$usage) yields: \usage{ f(FUN = *) } %- maybe also 'usage' for other objects documented here. without the backticks, which is of course found by R CMD check as syntax error. While this is easily fixed if the .Rd is further edited manually, I

Dear List, a second, more general, question concerning S4 classes. I have a bunch of functions/methods for my class. At the moment I have them as methods, because they work on objects of my S4 class and therefore "belong" to that class. On the other hand, it is comparably unlikely that someone else wants the same kind of method. And package.skeleton () produces the

Dear all, I just spent quite a while fixing a weird error in my vignettes while doing R CMD build and R CMD check R CMD Sweave ran fine, though. The cause turned out to be: 1. I have a data set flu, 2. and a corresponding vignette explaining things one can do with that object. This vignette creates another object flu (which masks the packages one). 3. Now when the next vignette is

Dear all, I just stumbled over the fact that subsetting by square bracket will only output the first given index. I guess the rest is thrown away by the CADDR in RenderSub (plotmath.c l. 1399). Maybe changing this could be considered as "low-priority desired" (would be nice if the output works for ? However, I suggest to announce the fact that only the first parameter is printed in

Dear list, dear Henrik, I find myself often reconstructing matrices from the result of rowSum (matrix) etc. I therefore propose a new argument, drop, for these functions: drop = TRUE (default) is the current behaviour. With drop = FALSE length (dim (x)) and dimnames are preserved and the affected dimensions are set to 1 (or whatever teh result length of the applied function is) I modified the

Dear all, I'm puzzled with matrix indices in plotmath. I'm plotting matrix elements: Z [i, i], and I'd like to put that as label. I'll describe what I want and what I get in LaTeX-notation. The output should look like Z_{i, i}, and my first try was plot (1, 1, ylab = expression (Z[i, i])) That, however, gives me Z_{i} (no comma, no second i) although the expression looks OK

Dear R-Developers, could 'sample' gain a ... argument? As a convenience function, I added a sample Method to my hyperSpec class. This function however has a flag indicating whether the results should be returned directly as a hyperSpec object or rather as indices that give a random sample. For the moment, I use SetGeneric to add the dots argument, but this of course gives a warning

Dear list, I'm stuck with looking for a function of the *apply family, which I suppose exists already ? just I can't find it: What I'm looking for is somewhere between sweep and mapply that does a calculation vectorized over a matrix and a vector: It should work complementary to sweep: for each row of the matrix, a different value of the vector should be handed over. Close to

Dear all, I have trouble with R-beta sweaving files that include definitions with \SweaveInput in combination with keep.source = TRUE Symptom: SInput is taken from too far down the input file (the shift is the number of lines of the included file). Is that known? Searching didn't turn up anything, yet I think there are more people than just me using keep.source. Example: $

Hi, I am currently analysis Raman spectroscopic data with the hyperSpec package. I consulted the documentation on this package and I found an example work-flow dedicated to Raman spectroscopy (see the address : http://hyperspec.r-forge.r-project.org/chondro.pdf) I am currently trying to remove outliers thanks to PCA just as they did in the documentation, but I get a message error I can't

Hello all. I'm using Samba 2.0.7 on Linux, and I've been having a problem I can't figure out. I was backing up a coworker's machine using the smbclient tar capability. He's got Win2k.

So, I got Quickbooks 2008 working in the latest WINE, and Ubuntu 11.04. Problems happen when I try and open an existing company file. It wants to update, and then updating fails, and then the whole shebang fails to load after that. I even tried copying the Quickbooks folder from the other system (just need to change the license) to make the updates more complete. Same exact problem. It crashes on
