hi I am trying to use the add-on package fdim to calculate fractal dimesionality of some time series data. I keep getting an error - trying to run simple example from the help pages Error in if (MaxDiff > Chi2) { : missing value where logical needed when I set the debug option of the function slopeopt() I get the following read out...

Hi, I?m new to R but I?m interested in using the fdim package to find the fractal dimension of a dataset. I downloaded the the package from https://cran.r-project.org/src/contrib/Archive/fdim/ and successfully installed it together with xgobi. However, when I try to run the first example, after df <- fdim(mydata,q=0,Alpha=0.3) I get the following error: Error in .C("pointdif",

Dear R-helpers, I am looking for an implementation of the box-counting algorithm to estimate the box dimension of a cloud of points in 3D (aka fractal dimension, or similarity dimension). The package 'fdim' might be doing this, but the documentation is awful and I don't understand what is what there. Does anyone know of an implementation of this algorithm in R, or elsewhere, or

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

R-users: My problem: the package fdim (which measures fractal dimensions of datasets) apparently prefers 3-D (XYZ) datasets. I'm trying to measure the information dimension (a type of fractal dimension) of a 2-D (XY) dataset. Here's some examples of the preferred 3-D data (XYZ): library(fdim) XYZ <- (makehplane(NumN=300, DimM=3, Longit=300)) fdim(XYZ,q=0.999999,PlotF=TRUE)

Hm, I am not an expert in this field but trying to use obviously old package which was removed about 5 years ago from CRAN is asking for problems. There is probably some incompatibility between recent R version and obsolete package. You either 1. need to install/compile R version from 2012 and install/compile this old package for this version. 2. Or you could try to find some similar

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 group. I am trying to install fdim on my win2000 os. this command is giving error and I feel I am not using it correctly, could some one show me why. install.packages(fdim, "C:\Program Files\R\rw1081\library" , CRAN = "http://cran.r-project.org", "internal", available = NULL, destdir = "C:\Program Files\R\rw1081\library", installWithVers =

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

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

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

Hi all, I wish to implement various landscape ecology measures through R, such as: box counting dimension; twist number statistics; contagion and lacuniarity indices; angular second moment; adjacency measures; dominance indices; etc ... Some of the measures can be applied to shape analysis and classification. Is anyone implementing any of these measures? If so I would like to contribute and

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

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
