fdim questions
...es 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 this: since fdim prefers XYZ...
