I tried to calculate the fractal dimension of a dataset using the box-counting method with R programming.
I used two packages:
The first one is fractaldim, specifically, the function fd.estim.boxcount.
The second one is Rdimtools, particularly the function est.boxcount.
The dataset utilized is
D <- read.table("http://archive.ics.uci.edu/ml/machine-learning-
databases/breast-cancer-wisconsin
/wdbc.data", sep=",", stringsAsFactors = FALSE)
I only used the numeric variables without standardization.
After that, I got the following plots from the first and second package respectively
I am not really sure about how to interpret the results of using these two packages.
Any ideas or example are appreciated?
Notes
I can edit the question for more details if you want.
This is not homework, I am just trying to understand the idea of fractal dimension using the box-counting practically.
