similar to: Recurrence plot in package "tseriesChaos"

Hello, I am an absolutely beginner with regards to R, so forgive me for my potentially very stupid questions. I have been attempting to create recurrence plots using R. The data I am using is based on a mutually exclusive and exhaustive coding scheme with over 40 individual codes which can be assigned to 6 higher order categories. When I carry out the usual rqa command, my plot is pretty much

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:

Dear all, I have uploaded to CRAN a new package: tseriesChaos. This is an early version (0.1) with basic tools for the explorative analysis of nonlinear time series motivated by chaos theory. Until now, the package is largely inspired by the TISEAN project (by Rainer Hegger, Holger Kantz and Thomas Schreiber: http://www.mpipks-dresden.mpg.de/~tisean/ ). This version includes: - Method of false

I get this on windows XP, rw2011, precompiled from CRAN: C:\R\rw2011\src\gnuwin32>R CMD build -- binary ./../library/tseriesChaos R CMD build -- binary ./../library/tseriesChaos * checking for file 'binary/DESCRIPTION' ... NO and there it stopped, while the following works: C:\R\rw2011\src\gnuwin32>Rcmd build --binary ./../library/tseriesChaos Rcmd build --binary

Dear Sir, I’am a new user of “R” Software. I thank you very much for this Software. By running the “R” 2.3.0 software I have encountred aproblem: I have downloaded the tseriesChaos package from CRAN. When I try to run any function of the the tseriesChaos package for example, the c2 function the “R” software diplays on the screen ‘error, impossible to find the c2 function). Please help me! What

Dear Sir, I’am a frensh student and i’am a new user of the R software. After using the command (x<-read.delim(“clipboard”) to read a spreadsheet of Excel, I want to run the bds test and calculate the Lyapunov exponent. I have charged the R software by the packages tseries and tseriesChaos. when i run bds.test(x,m=2) Unfortunately the R software displays “error in as.vector(x,mode= “double”) :

Hi! Is there any package on CRAN that uses Fortran-90/95? I would like to study it. Thanks, Gregor

Hi -- I have found a bug in an HPC code where llvm is vectorizing a loop on Skylake that has an obvious recurrence. I derived a small test case based on the original benchmark below: /*****************************************************************/ static void __attribute__ ((always_inline)) one( const int *restrict in, const int *const end, const unsigned shift, int *const restrict index,

Dear developers, Thanks a lot for designing HDT. It is really a great tool to have. I have come here to know more about the usability of HDT. HDT is called by syslinux. What to do if I like to call it by grub2 ? and what to do if I like to run within my debian box ? Thanks

Hi, After reading the paper entitled "The Computation of Line Spectral Frequencies Using Chebyshev Polynomials", P. Kabal and R. Ramachandran, IEEE Trans. on ASSP, Vol. 34, No. 6, December 1986, I rewrite the function cheb_poly_eva in lsp.c using the Clenshaw's recurrence formula, as described, for example, in Numerical Recipes in C, Second Edition (5.5 and 5.8) : static float

I don't expect much improvement, but it makes the code simpler, especially for memory. Would also have to test on fixed-point and see if it works. > Maybe a new implementation should use the algorithm

Are there any packages that help with statistical analysis in situations where fractal geometry is relevant? Perhaps something that supports computation of fractal related statistics, such as the Hurst exponent or fractal dimension? Or perhaps which support obvious tasks such as taking samples from a dataset at different levels of granularity (such as sampling spatial data at cm, m, km

Dear R users, I would like to calculate a cumulative sum as following: on the i-th row, in the j-th column of a matrix, I would like to obtain the sum of the (i-1) preceding elements of this j-th column.

Question, testing the waters to see if anyone has input on this. My summary belief is that I'm seeing a problem with the PXE bios code causing this issue. I'm trying to find out what else I can do to confirm that, and rule out pxelinux/. I'd like to get a confirmation that the use of pxelinux isn't a factor, as I'm not using 'keeppxe'. I'm rolling out a

Hi, I am wondering if there is a simple way to plot MCF(mean cumulative function) for recurrent events in R? MCF (http://www.weibull.com/hotwire/issue57/relbasics57.htm) And do you have some other recommendation in visualize recurrent events? I did some research online. Some people use ggplot2 to plot MCF, but it requires some additional coding. http://user2010.org/slides/Shentu.pdf Your help
