fdim questions
...he 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) Here's an example of the type of data I have: library(fdim) X<- sample(1:1000,size=300,replace=TRUE) Y<- sample(1:500,size=300,replace=TRUE) XY<- matrix(c(X,Y),nrow=300) fdim(XY,q=0.999999,PlotF=TRUE) My question is thi...
