I take the liberty of pasting the on-line documentation for package "wavelets", functions "dwt" and "wt.filter", pertinent to the wavelet/filter choice. While I apologize for my verbose messages with huge attachments, I encourage whoever loads packages to CRAN to take some minutes to reread the attached documentation. Usage dwt(X, filter="la8", n.levels,

Is there a wavelet toolbox in R available that can be compared to the Matlab toolbox for wavelets. Does this toolbox offer the possibility to calculated approximations with different wavelets such as Daubechies 2, Daubechies 3, etc, Symmlet 3, Symmlets 5, etc, Coiflets and so on. I have tried to proceed in this way but I was only able to use one sort of wavelets with a pre-fixed order (i.e.

Hello, I have to make use of the Cohen-Daubechies-Fauraue (CDF) 9/7 wavelet-transform, but have not found these biorthogonal wavlet in the released packages waveslim, wavethresh or wavelets. Is there any package doing this transform? Or can anybody send me the function doing this? I would be very grateful of that. Thanks Annika

After a year my R programming style is still very "C like". I am still writing a lot of "for loops" and finding it difficult to recognize where, in place of loops, I could just do the same with one line of code, using "sapply", "lapply", or the like. On-line examples for such high level function do not help me. Even if, sooner or later, I am getting my R

I've been reading up on wavelet transforms the past week, and I plan to start on some video compression stuff next week, if it's any good (small chance :)) for Tarkin. So far I think I know what's happening, however there's one small thing I don't quite understand yet. If I understand correctly, you can do a 2d wavelet transform (I'm assuming a Haar transform here for

Hi everyody, ince some of you asked for references, here some links: A good book is 'Data Compression' from David Salomon, ISBN 0-387-98280-9. Papers available on the web: A nice introduction to wavelets is http://cm.bell-labs.com/who/wim/papers/athome/ A somewhat theoretical paper about integer wavelet transform http://cm.bell-labs.com/who/wim/papers/integer.ps.gz Since Peter

Hi, All, I have come across a problem building a DLL from .f90 source (R 2.3.1, Windows XP). When using the R CMD SHLIB procedure, the DLL itself was being built, but its export table was empty. Among the output from R CMD SHLIB the following message appeared: c:\mingw\bin\nm.exe: 'a.out': No such file The reason is the empty list of dependencies in the pattern rule for DLLs

I have been revising some FORTRAN 77 routines in R packages I have previously submitted. Since R is now using gfortan I experimented with some Fortran 90 code (array intrinsics primarily). So far the code is still in F77 fixed format, in files suffixed .f (not .f90), but incorporates some F90 constructs. It has worked fine in linux/R. I tried to follow the thread of previous discussions

Following the setup in Prof.Duncan Murdoch's page, I have successfully compiled the DLL for one Fortran 95 program using Gfortran and got 300 times speed boost.

Hello, I work under windows xp and I am trying to build a R package with a subroutine written in fortran 90. I have installed all the updated tools and I am working with R-2.4.0 or R-2.5.0. When I check a package with a subroutine in fortran 77 (and extension f) everything is ok. When I try to build the same package with a subroutine in fortran 90 (with extension f90) the following warning

Hi all, I'm porting a package that I've worked on for OS X to Cygwin/Windows. This package requires a Makefile. My question is, how can I find out (or what is), the link command?

Hi all, (Originally posted to r-help) I'm porting a package that I've worked on for OS X to Windows. The package is written in F95 so I need to compile it with gfortran and link it with gcc4. I've been trying to build an R with gcc4 without luck so far. If there is a binary of such a thing info would be appreciated. This package requires a Makefile. My question is, how can I find
