Dear helpers, I am trying to use the mda package downloaded from the R website, but the data set has missing values so I got an error message. Should I manually handle these missing values? I was trying to read the documents to specify any option related to missing values, but I did not find it. Please forgive me if I ignore something obvious. Thanks, Zhu Wang Statistical Science Department

Dear all, Is there any generic algorithm code for optimization implemented in R? I searched without success. Thanks, -- Zhu Wang Statistical Science Department Southern Methodist University Phone: (214)768-2453 Fax: (214)768-4035 Email: zhuw at mail.smu.edu

Dear helpers, I am trying to create a library which uses some Fortran source files and Lapack and Blas subroutines. The Fortran source files from the original author contain subroutines isamax.f, sgefa.f and sgesl.f, which are part of BLAS subroutines on my Linux computer, but maybe different (old) versions. So in addition to these subroutines, there are other Lapack and Blas subroutines

Dear helpers, I am trying to write a function to return prediction values using package ts. I have written three different versions since I am not sure what's wrong with my func2. func and func1 return the same results.But func1 and func2 don't. In particular, the only difference between "func1" and "func2" is the function variable name being y and data, respectively.

Hello, I use wavethresh packages to perform wavelet analysis. In particular, I would like to compare 2 signals (vectors) after a wavelet decomposition. I would like to use cor.test function, but this function acts on the entire vector values. I plan to perform a cor.test on each level of the wavelet decomposition, say N. So I will have at the end of a first step N results of cor.test. How can

Dear helpers, When I use ar to fit the data with length 180, I have the following error: ar(x,method="burg") Error in acf(x, type = "covariance",lag.max=order,plot=FALSE): lag.max must be at least 1 If I use ar(x), then I have Call (x=x) order selected 0 sigma^2 estimated as 5374 Obviously I missed some points for using ar. This is R 1.7.0 under Redhat Linux

Dear all, I have a problem to build a package on Windows XP while there is no problem on Linux.

Airon, I used R2.4.0 on a Windows XP (SP2) (not Chinese :-)) and it still works: > data = read.csv("u:/airon.csv") > xdata = data$Adj..Close > modwt.la8 = modwt(xdata, "la8", n.level=6) > summary(modwt.la8) Length Class Mode d1 1467 -none- numeric d2 1467 -none- numeric d3 1467 -none- numeric d4 1467 -none- numeric d5 1467 -none- numeric d6 1467

Hello, I have upgraded from Mandrake Linux 8.0 to Mandrake 8.1 and try to reinstall my favourite R... Everything is OK for the base software but I have trouble to get some packages installed. Specifically, for some packages, a "collect2" binary seems to be necessary during the compilation/linking process of the library, and LD complains about not finding it : Installing source

hi everyone . I am trying to use some packages but there are some functions have the same name in different package. for example dwt function both in packages wavelets and waveslim dwt(X, filter="la8", n.levels, boundary="periodic") How can I avoid mixing them up ? -- TANG Jie Email: totangjie@gmail.com Tel: 0086-2154896104 Shanghai Typhoon Institute,China

This code consistenly segfaults for me. Can someone please take a look and tell me if the problem is due to something I am doing or is there a problems with the dwt (idwt) functions in the waveslim library. Thanks tom library(waveslim)

Can someone please help me understand the examples given in the dwt function of the waveslim library library(waveslim) ?dwt I'm having a problem understanding these lines. I assume they are required because of how the algorythm deals with the signal bounderies. Am I correct in thinking that for wavelets of scale 1 and 2, the coefiecints need to be shifted by 2 places, for scale 3 and 4 shift

Airon, I don't think you have to find an English computer 'cause the following must work in your Chinese one :-) Let me explain. First of all, change your lines to xdata <- ckhdat$Adj..Close[1:1447] #names(ckhdwt.la8) <- c("w1", "w2", "w3", "w4", "w5","w6", "v6") note the # sign, i.e., DO NOT change the names

waveslim 1.4 has recently been uploaded to CRAN and is fully compatible with Rv2.0. Besides ensuring usability with the most recent version of R, two additional "flavors" of wavelet methodology have been added to the package: (1) Hilbert wavelet pairs and (2) the dual-tree complex wavelet transform [only 1D and 2D ported from Matlab code by Selesnick]. The dual-tree CWT code has

Bonjour, J'aimerais savoir si quelqu'un pourrait m'aider en ce qui concerne l'utilisation du package waveslim. Je voudrais savoir comment on fait pour revenir a un signal d'origine lorsque l'on dispose de coefficients de detail et d'approximation. Merci d'avance Tuleau Christine (christine.tuleau at math.u-psud.fr)

My Windows machine has gone "kaput" and I am trying to see how R might work on my Mac. I am interested in using the contributed packages, especially "waveslim" and "wavethresh". Are all packages available under either Windows, Mac, or Unix? I can't seem to tell from the documentation whether this is so (probably because I am not very computer literate!). Any
