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...

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 e...

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 10 [1] 2734 11 [1] 2733 12 Error in slopeopt(AllPoints, Alph...

...ome 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 package for recent R. 3. Or you could check source code for fdim and reprogram it to get rid of the error. My recommendation is to try option 2 first. And keep your messages posted to rhelp as others my give you different insight. Cheers and good luck.

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 uses the fdim package successfully and can help me out? thanks, Remko ---------------------------------------...

...pied by the crystal. Since the image can be converted to grayscale, I figured that specifying an intensity threshold would allow me to differentiate between crystal and surrounding solution. I know this can be done in Matlab, but since I'm more comfortable in R can it be done in R? I found the fdim package but that calculates the dimension for a data.frame - but I'm not sure whether this would be feasible for my image. Any pointers would be appreciated ------------------------------------------------------------------- Rajarshi Guha <rxg218 at psu.edu> <http://jijo.cjb.net> G...

Dear list, I'm seeking some advice regarding a particular numerical integration I wish to perform. The integrand f takes two real arguments x and y and returns a vector of constant length N. The range of integration is [0, infty) for x and [a,b] (finite) for y. Since the integrand has values in R^N I did not find a built-in function to perform numerical quadrature, so I wrote my own after

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
