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

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

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:

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:

Any sollutions? I'm using latest Wine on x86_64 Arch Linux.
Thanks.

fractal image analysis
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?

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

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

[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

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

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?

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

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?

Does anyone have any code for Fractals, chaos,
or anything like that, please?
This is strictly for demo purposes...decorative only.
This is R version 1.5.1 for Windows.
