....11 (but of course windows binary). Usually, there is no problem in doing this and all objects work as expected. I am often doing this to be able to produce wmf or emf graphic files that I need. This time I had some spectra that I have taken the first derivative of with the sav_gol function in the RTisean package. I know RTisean is just an interface to the Tisean executables. The trouble I am facing is that it seems that the location of the Tisean executables is somehow hard coded to the R workspace file. I assume this since when I try to rerun the sav_gol on the windows machine after copying the w...

...nction on my own data, I get the following message. Waiting to confirm page change... Error in .checkPath(path) : no TISEAN executables found in that directory. Please set a proper TISEAN executables path using 'setTISEANpath' I?ve tried setting the TISEANpath to the directory where the RTisean library is on my computer. Could someone please suggest what the problem might be?

I have a question on generating multivariate time series surrogates using the "surrogates" function in the RTisean library. The surrogate data matrices are always much shorter than the input matrices. FYI, I'm using R version 2.12.2 on Windows XP RTisean library v 3.0.14 Tisean algorithms v 3.0.13 Creating a surrogate univariate time series returns a time series with the length of the original vec...

Dear R users, I've just uploaded 2 packages on CRAN, RTisean and tsDyn, both for time series analysis (joint research projects with members of the Statistics Department, University of Udine). Brief descriptions follow. RTisean is an R interface to TISEAN executables (http://www.mpipks-dresden.mpg.de/~tisean/). TISEAN is a suite of C and Fortran routines for...

Dear R users, I've just uploaded to CRAN a new version of RTisean, the TISEAN-to-R interface. This is now compatible with the recent, new 3.0.1 release of TISEAN [1]. This new TISEAN version is explicitely GPL-ed, and has some more routines handling multivariate time series. Bests, Antonio, Fabio Di Narzo.

...o http://bit.ly/98dZsi and I trust some progress has been made ever since. I was able to find some functions in the packages http://cran.r-project.org/web/packages/Rwave/index.html and http://cran.r-project.org/web/packages/fArma/index.html Allegedly, there should be functions for this in the Rtisean package http://cran.r-project.org/web/packages/RTisean/index.html but I have not been able to find them. Bottom line: if you have a time series (list of empirical data of varying length and not necessarily sampled on a uniform time grid) what R tool would you use to estimate its Hurst exponent? A...

I want to run deconvolution of a time series by an impulse or point-spread function through Wiener filter, regularized filter, Lucy-Richardson method, or any other approaches. I searched the CRAN website and the mailing list archive, but could not find any package for such a deconvolution analysis. Does anybody know an existing R function for deconvolution? TIA, Gang

Hi When we use the sav_gol command in R , it shows an error which says: " error in as.matrix". We've downloaded the necessary packages. Kindly help us with this issue. If there is any other function to perform Savitzky-Golay smoothing in R, please let me know. With Regards Reynolds

Hi R-Users I need to estimate Lyapunov exponent of my time series. After reading description of all functions available I still don't know how to determine time delay. My time series length is 4200. Is it possible to determine time delay with other function's output or I can choose any random value? Thanks for your help! -- View this message in context:

Hello, R-devel seems to be the appropriated list for what I'm to ask: soory if I'm wrong. I am a c newbie but nevertheless I am trying to 'couple' an extern c software with R. The compiled library is actually a stand-alone c program, which uses text file for input and output. It uses *lots* of differents and (to me) rather complicated and nested "struct"s to represent
