Dear R users, I am looking for code to perform a permutation version of the multivariate two-sample test (difference in means). I am aware of F. Pesarin's book and website, but his single S-Plus function does not work in R (for various reasons). Has anyone adapted (or added to) PermutationTestMeans() so that it does work in R? Or do you know of an alternative implementation that does

Hi everyone I am using the wavelet and waveslim package in R to find the wave variance.Here is the code return.modwt<-modwt(X, filter="la8", n.levels=5, boundary="periodic", fast=TRUE) return.modwt.var<- wave.variance(return.modwt, type="nongaussian") Where X is a uni-variate time series. I am expecting a matrix with 5 rows(no. of levels) and 3

Dear R Users, For running wavelet functions using dwt( ), modwt( ), and mra( ), a wavelet filter algorithm is applied. For all these functions, default is "la8" and other possibility is "haar". In related documents, another possibilities like as symlet and coiflet ... are not cited. Besides "la8" and "haar", which wavelet filters can be used? Thank

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

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)

Airon, I'm not sure I have understood your question. Anyway, it seems to me that you'll have to code a little. Take a look at ?modwt. I think you'll have to put zeros each scale a time except the one you want to reconstruct. Then do imodwt. After some small loop, I think you'll get the desired result.

Hi: I have encountered problems with imodwt and universal.thresh.modwt and cannot find any reference in R Search. Hope someone can give me some ideas: Starting with modwt.la8 <- modwt(xdata, "la8", n.level=6) <-- this seems to work fine (1) ydata <- imodwt(modwt.la8) will always give ydata as numeric(0) (no values) instead of being a time series data with

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

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

Hi all, I am running dovecot on a linux server (FC3) in conjunction with Sendmail. My configuration is quite vanilla and I am having the following problem: occasionally (once every 3-10 days) the dovecot server will become unresponsive and attempting to access mail via pop3 will produce an error message on the client side. As best as I can tell, the dovecot process dies because if I restart it

Hello! I'm not a newbie to Linux but to Samba and Linux<->Windows networking, so -naturally- I encountered some problems.

And this is my smb.conf [global] workgroup = TEST netbios name = hilbert interfaces =

After fixing princomp(), recently, {tiny negative eigen-values are possible for non-negative definite matrices} Fritz Leisch drew my attention to the fact the not only eigen() can be funny, but also svd(). Adrian Trappleti found that the singular values returned can be "-0" instead of "0". This will be a problem in something like sd <- svd(Mat) $ d

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

Dear list members, I have problem to load data of the library waveslim. After I load the library waveslim and tried to load data ibm data(ibm) Error in file(file, "r") : unable to open connection In addition: Warning message: cannot open file `ibm.txt'' I also tried other data sets without success. It works for other libraries though. Any suggestions? Thanks. Zhu Wang

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
