fractal vs. Fractal packages
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

Interface between fractal geometry and statistics
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

fractal package
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) >

Fractal Explorer is messy
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

Detrended Fluctuation Analysis (fractal pkg) troubleshooting
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

fractal dimension of an image
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

[SoC 2009] will R Foundation participate? project proposal: fractal analysis
Hello R developers, I know it is still a bit early to talk about Summer of Code, but I wish to know what are, approximately, plans for this year. Last year I applied as a student under OSGeo with a QGIS-R project and had a very positive experience [0], therefore I plan to participate again. I found an interesting hint [1], about implementing fractal analysis in R, and a would-be mentor has

problems with cygnus fractal extreme
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

Anything for fractals ?
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

Fractals with R
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

Mann Kendall mutation package?
Hello - does anyone know whether there are any packages for Mann-Kendall mutation tests in R available? The only one I could find online is this MK_mut_test: Mann-Kendall mutation test in Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel.

interlaced / fractal encoding
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

Matrix to data frame conversion
I have a matrix which I wanted to convert to a data frame. As I could not succeed and resorted to export to csv and reimport it again. Why did I fail in the attempt and how can I achieve what I wanted without this roundabouts? The original matrix: > str(comb_model0) num [1:90, 1:4] 3.5938 0.0274 0.0342 0.0135 0.0207 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:90]
