similar to: [SoC 2009] will R Foundation participate? project proposal: fractal analysis

Hi all, here's a proposal for a SoC project on wildlife movement patterns analysis. A MSc student is available to anwser the call, of course. The idea has already been briefly discussed with the mantainer of the adehabitat package and the AniMov project community. Short description Develop some add-on functions to use the adehabitat package to perform basic movement ecology analysis, in

Dear R People: At one time, there were packages called fractal and Fractal, respectively, which had different functions. I can't seem to find Fractal any more. Does it still exist somewhere, please? Thanks in advance for any help! Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess

Dear list, there seems to be a problem with the standard location of R?s 64-bit libs at least under openSUSE. I had two user questions regarding the compilation of rpy2 for 64-bit systems. Personally I don`t know rpy2 but maybe someone on this list can decide if the mistake lies on R`s side or on rpy2?s side or in between. R-devel is installed in these cases, I asked. Latest R-base or

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

https://rdrr.io/rforge/fractal/ https://cran.r-project.org/web/packages/fractal/fractal.pdf Hi, I am trying to learn about nonlinear time series, and fractal time series analysis in particular. I am interested in becoming proficient with the 'fractal' package. I have two specific questions: 1. I have a basic understanding of ARMA and ARIMA models. Can someone recommend

Greetings of Peace! I am new in R software. I want to use the correlation dimension corrDim in computing a map. I have installed the packages(fractal) in R. Now my problem is this, when I tried your example in the following site http://rgm2.lab.nig.ac.jp/RGM2/func.php?rd_id=fractal:corrDim  > library(fractal) > png(filename="corrDim_%03d_med.png", width=480, height=480) >

Hello, I want to use Fractal Explorer, which is freeware and available from http://www.eclectasy.com/Fractal-Explorer/ ,under Wine. It mostly works, however the main window doesn't redraw correctly, it shows the background. This image shows what happen: http://img10.imageshack.us/img10/3786/blahqnm.jpg Any sollutions? I'm using latest Wine on x86_64 Arch Linux. Thanks. -- Renan Birck

Dear all I tried to find some packages (or programs) for image analysis and especially fractal dimension image analysis but so far I had not success. It shall be used for particle surface layer analysis from TEM images. Any suggestions? Best regards Petr

Hello, I have a problem that I think can be solved in R but I'm not sure how to tie things together. I have a digital image of a crystal growth in 2 dimensions. And my aim is to calculate the fractal dimension of the crystal. I was planning to use the box counting method. So I need to read in the image in R (for which I can use the pixmap or rimage packages) and then draw a grid over at a

I'm working with the DFA (detrended fluctuation analysis) function in the package fractal on postural sway data, and for the life of me can't get the results to turn out as they should given what my data looks like. The data resemble a random walk, but the Hurst exponent estimates that I'm getting at ~0.9 instead of ~1.4, which is the value a researcher I've been working with

Hello Does any one know what is the complexity scale of fdim "fractal calculation function", I need to find O(N) function to do fractal calculation. Thanks a lot

Hello I am getting this Error in slopeopt(AllPoints, Alpha) : Object "LineP" not found when the dim(<data.frame>) of the data matrix for which the fdim is being calculated hits a certain values depending on the data set. e.g print(dim(mat)) fd <- fdim(mat,q=2) [1] 2743 2 [1] 2742 3 [1] 2741 4 [1] 2740 5 [1] 2739 6 [1] 2738 7 [1] 2737 8 [1] 2736 9 [1] 2735

Hello to everybody, Does anyone know if the Fractal dimension (an MDS technique looking the intrinsic dimension of data) is available for R?

i cannot seem to get this app to run properly in wine. Bruce, who is the programmer of it, told me he would be happy to make whatever changes are necessary to make it work with wine, so if it's something on his end, could somebody on the team reach out to him and help him get it going? his website is: http://cygnus-software.com/ I love fractals, and want to take full advantage of my i7

Can anyone tell me if it is possible to encode music in an "interlaced" format.. perhaps I should explain what I mean by this. Say I'm getting 1k/sec off some guy's modem on opennap. It would be sweet if I could listen to the song as it is downloading but obviously the quality is gunna suck. So suppose the song was encoded in this interlaced fashion, I would be able to

Dear all, I have uploaded to CRAN the version 1.8 of the package 'adehabitat'. Significant changes are listed below: * getverticeshr now relies on the function contourLines(), and returns smoother estimates of the kernel home range (see the help page). * the new function kernelkc (and related functions) now allows the estimation of the utilization distribution in space and time of

Hallo, I am a newbie to R and desperatley seeking some material about fractal geometry. I found the great library on wavelet analysis of images and I'm now also keen on finding a similar package for calculating fractal parameters for given images. Does anybody know something about such a package? Every hint is greatly appreciated!! I searched already the database, but did not find anything

Hi everybody, I put some R-code to a web page for drawing fractals. See http://fractalswithr.blogspot.com/ If you have some R-code for fractal images, I'm willing to include them to the page. Has somebody tried L-systems or Markov algorithm (http:// en.wikipedia.org/wiki/Markov_algorithm) with R? Best wishes, Atte Tenkanen University of Turku, Finland

Hola Quisiera saber si podrían informar como puedo hacer para obtener fractales de una imagen con R. Hay algún paquete? o tutorial que me guíe? Desde ya muchas gracias. Atentamente, Luis
