...eta, and my system is Ubuntu 9.10 64 bit (though that probably doesn't matter). Building the example file I also found that \SweaveInput{} cannot be followed by anything else on the line(not even a LaTeX comment). \SweaveInput{x}y complains that file xy is not found.

Dear R users, Here is my problem: I have an array with at least four dimensions: > dim(myArray) [1] 20 17 3 6 I'd like to apply a function to each occurrence of the matrix (3x6) defined by the last two dimensions. This interpolation function always return a matrix of the same dimensions as its argument: > interpSecteurs.f(myArray[1, 1, , ]) secteur rotation 1 2 3

...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 stumbled over it using the automated .Rd generation with inlinedocs - in this combination it is very inconvenient. Any suggestions?

...stood the concept of namespace correctly, a package with a namespace avoids trouble with clashing function names - so I don't need to worry about that using functions (I anyways have some functions, that should not be methods of the class).

...tions - but I didn't see anything that just works with irregularly spaced signals: all functions I found take only the signal, not its x-axis. Where should I look? Or am I lacking some math that tells how to do without the frequency axis?

...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 that the base function sample is overwritten (and my colleagues are almost as scared of warnings as of errors...)

Greetings. I'm teaching linear regression this semester and that means I write more functions for my regression support package "rockchalk". I'm at a point now were some fresh eyes would help, so if you are a student in a course on regression, please consider looking over my package overview document here: http://pj.freefaculty.org/R/rockchalk.pdf That tells how you can grab

...function is partly also because I want to overload the functionality for a specific class and I don't think it's a good idea to invent a name for something that probably already exists. If this function does not exist, any ideas how I should call it?

Dear Group, I am looking for ways to use R and Matlab. Doing the data transformations in R and using the data in Matlab to analyze with some pre-defined scripts. Any good ways to transfer the data into matlab in its most recent version? I tried using R.matlab but the writeMat output is not readable by Matlab. I just need to output a data.frame and read it as is into matlab where I can do any

I'm attempting to sort a 3 dimensional array that looks like this > x , , 1 [,1] [,2] [1,] 9 9 [2,] 7 9 , , 2 [,1] [,2] [1,] 6 5 [2,] 4 6 , , 3 [,1] [,2] [1,] 2 1 [2,] 3 2 Such that it ends up like this .... > y , , 1 [,1] [,2] [1,] 2 1 [2,] 3 2 , , 2 [,1] [,2] [1,] 6 5 [2,] 4 6 , , 3 [,1] [,2]

Dear all, I have run into a problem when running some code implemented in the Bioconductor panp-package (applied to my own expression data), whereby gene expression values of known true negative probesets (x) are interpolated onto present/absent p-values (y) between 0 and 1 using the *approxfun - function*{stats}; when I have used R version 2.8, everything had worked fine, however, after updating

Hi I am used to handle bio information such as NMR data or IR data . I want to perform pls regression, so I search the help page of plsr. and I use the example of plsr. But I have a problem to make appropriate data format to do plsr. these example data type like this : A data frame with components NIR Numeric matrix of NIR measurements density Numeric vector of densities train Logical vector

HI, Dear R community, I want to know how to select the optimal decision threshold from the ROC curve? At what threshold will give the highest accuracy? Thanks! -- Sincerely, Changbin -- [[alternative HTML version deleted]]

HI, Dear R community, My data set has 2409 variables, the last one is response variable. I have used the nnet after feature selection and works. But this time, I am using nnet to fit a model without feature selection. I got the following error information: > dim(train) [1] 1827 2409 nnet.fit<-nnet(as.factor(out) ~ ., data=train, size=3, rang=0.3, decay=5e-4, maxit=500) # model
